There are statistics that show that governments (mainly socialism and communism) have, in recent times, killed many more people than murderers, or even wars, did. It's a phenomenon called democide.

Some famous people that call themselves libertarians are the linguist Noam Chomsky and the Nobel-prize winning economist Milton Friedman. They have wildly different visions about how the economy will function without a government, but both agree government should not intervene into it.

Somalia is often alleged to be evidence of the lack of a government causing violence. However, in 2004, after being stateless for more than a decade, its murder rate was less than half of the Africa's average murder rate. Many say it is primarily because guns are hard to acquire there, though.

About Libertarianism

UPDATE on 13/09/2021: You may be interested in reading my essay about political blindness. It is much more well-written than this blog-post is.

UPDATE on 29/07/2022: I have made a YouTube video about libertarianism (if you cannot open it, try downloading this MP4 and opening it in VLC or something like that) that summarizes many of my political views.

TL;DR: If we should have a government at all, it should be one based on science. And modern-day social sciences, and (perhaps especially so) fields of science that combine natural and social sciences, are not yet scientific enough to allow us to base governments on them. Modern-day social sciences usually just give governments false confidence that their policies are correct and, to quote Clive Staples Lewis, forbid wholesome doubt. Therefore, we should not have a government. If we were perfect, then we should be living in a technocratic dictatorship. But, clearly, we are so far from perfect that anarchy is better. I became a libertarian because government-backed-up pseudosciences put my mother and almost my father in jail.

The word "libertarianism" is defined as "a belief in human free will". Now, the phrase "belief in" has two quite distinct meanings: one is the belief that something exists, and the other one is the belief that something is reliable.

Green Polar Rose-
One of the symbols of
In politics, it's mainly used in the second sense. In fact, as a political libertarian, I am not even sure whether free will itself is an illusion, and that seems quite a bit irrelevant to me. The basic principle of libertarianism (called non-aggression-principle) is that initiation of force is always immoral. The same applies to the things where other people (libertarians call people who are not libertarians statists, from state, a rare word meaning country or government) believe that it's justified, like the police.
Libertarianism has a bad name. Its adherents are often said to be selfish and greedy. But the same is true for many other political opinions that aren't popular. That's because its arguments aren't communicated in a good way (they're often accompanied by things such as global warming denial, or nonsense and insulting phrases such as all cops are bastards), or worse, they aren't being communicated at all.

WARNING: The following text contains things that some people (especially in Croatia) might find insulting. It was not intended that way, but I can see how it could. It's nothing racist, nor against LGBT individuals, nor against feminism, nor does it support communism, or anything like that. I suppose it can also be depressing to some people, but it is better to be a realist than an optimist. If you are ready to read it, click here.

I hope the way I communicated the libertarian ideas made you think. I realize that they are hard to accomplish, because many people like the false sense of security and justice the laws give them. But the first step towards achieving some political goal is to speak out about it.
It's difficult to convince people to value freedom. It's much easier to convince them that giving up liberty somehow makes a society better. It's instinctual to think that taking away peoples' freedom and controlling what they do somehow makes them more economically efficient. And maybe if human beings were perfectly rational and had access to perfect information (so that game theory could be used to model human behavior), these instincts would be correct. Those instincts are why we had the things such as slavery, fascism and communism. And violent revolutions are, exactly because of that, counter-productive. If the vast majority of people believe government is necessary for safety, overthrowing a government usually leads to an even more oppressive government forming. Even when you do convince people to value freedom, there is often a state holding them back. For instance, the government was one who was putting the liberators of the slaves into prisons.
Democracy is arguably better than theocracy, in fact, as I explained in my blog-post about atheism, I believe theocracy is the worst form of government, because it is most immune to logic and evidence showing its policies are bad. But that does not mean that, if you try to install a democracy in a theocracy such as Afghanistan, you will succeed. In fact, attempting to install democracy in a country where people are indoctrinated into thinking theocracy is good and that education is bad (no idea how they make that compatible with Islam in their heads), is arguably counter-productive. I think all countries are like Afghanistan in that regard, having indoctrinated population not willing to fight for good principles, in fact, they are indoctrinated to fight against them. Almost everybody these days, and the same is true in history, is indoctrinated into thinking government overreach is not an issue, or at least not as big of an issue as it actually is.
In a world in which people were rational, or at least a significant percentage of people was rational (so that they would make a good government), eugenics and government telling people what to eat would certainly be good things. Government overreach would not be a concern. In the imperfect world where we live, we need to make trade-offs between the useful things government does and avoiding government overreach, and the trade-off that avoids government overreach is, as far as I can tell, always better. In a rational world, it would be a good thing to get rid of genetic diseases by preventing people with them from procreating. In real world, we need to ask ourselves how big the intended effects would be, would government even do those things properly, and whether it is worth the government overreach. Given that only around 3% of deaths are caused by a known genetic anomaly, eugenics would be a giant government overreach with, at best, minimal health benefits. Also, real-world governments that tried to do eugenics arguably did not do it properly: killing entire ethnicities with no evidence of genetic disease (as Nazis were doing) will, if anything, make our gene pool less fit, rather than more. Nutritional scientists mostly agree that around 17% of fatal heart disease these days is caused by saturated fat. The associations between sugar and type-2-diabetes and between heme iron and colon cancer are significantly weaker. So, given that around 11% of deaths are due to heart disease, government forcing people what to eat will, at best, reduce the number of deaths per year by around 2%. Would that be worth the government overreach? I do not think so. Especially not since real-world governments do not seem to give proper nutritional advice, so the actual decrease in mortality will be way less than around 2%, if there would be any at all (It is hard to tell how many deaths are indeed caused by inadequate nutrition. There is this perception that Vitamin K deficiency, agruably the biggest cause of heart disease historically, is gone, although the evidence tells us otherwise. There is also this perception that scurvy is gone, when, in fact, around 12% of people these days suffer from Vitamin C deficiency, the vast majority of that being undiagnozed or wrongly diagnozed as something else. I have asked a Quora question about it. Nevertheless, I do not consider that relevant, as the government cannot address the problems it refuses to acknowledge even exist, that are widespread Vitamin K and Vitamin C deficiencies.). Some people think a significant percentage of COVID-19 patients would have been saved by government forcing people to follow a good diet, but, in my opinion, even that is questionable. Suppose everybody in some country has type-2-diabetes, that makes COVID-19 deadly. In that country, who would be those people spreading COVID without realizing they are infected? Almost nobody, right? Which is presumably why COVID-19 did not spread as much in countries most plagued by type-2-diabetes, that are Sudan and Papua New Guinea. Slightly decreasing type-2-diabetes in Sudan or Papua New Guinea would obviously lead to more COVID-19 deaths, rather than less. Relationship between rates of type-2-diabetes and COVID-19 deaths is obviously a Laffer Curve it is hard to tell where the peak is and whether we are on the left of that peak or on the right of that peak. And let's not forget there are some rare germs, such as the Bird Flu, which kill people by turning their immune system against them, and good diet in a Bird Flu pandemic may even be counter-productive. And the same probably goes for your ideas about what the government should do: it would have, at best, minimal benefits, while resulting in a lot of dangerous increase in government power.
Achieving libertarianism would require a giant paradigm shift in the way most people think about politics. People usually consider sovereignity of countries to be a good thing. Libertarians do not, we hate the idea that some fallible government should have absolute power. People usually consider equality before the law to be a good thing, except, in recent times, for vaccination companies. People have started to realize holding vaccination companies liable for incredibly rare (if real) severe side-effects of vaccination discourages investment in this essential business and does more harm than good. Hopefully people will soon realize the same is true not just for vaccination (Elon Musk, for example, seems to realize that, when he said that the only way to innovate in today's society is to ignore the laws and hope nothing happens to you because of that). Most people consider rule of law to be a good thing. But rule of law only makes sense if laws are good, and libertarians think the vast majority of laws we have are bad, and that it is a good thing they are not always enforced. Most people think corruption is always bad, that it is never a good thing if the government breaks its own laws. Libertarians think corruption is a symptom of a bigger problem of stupid senseless laws, and that eliminating the corruption while doing nothing about the underlying problem often does more harm than good.
People tend to think it is important who is on power, and that, if they were on power, things would probably be better. For example, people tend to describe Dalai Lama and Mao as mass murderers. In reality, if you were in their shoes, you would probably have done the same, afraid for your life and realizing how powerless you actually are. Imagine that you are Dalai Lama receiving a letter saying "We are about to do some ritual, and, for that ritual, we need this-many cut-off hands and this-many cut-off heads. Order your army to kill or mutilate some Chinese people to deliver that to us... or else we will kill you and replace you with somebody else.". What would you have done? What would you have done if you were in Mao's shoes when he went to investigate reports of mass starvation in Henan, and people there replanted rice from multiple acres into one to make it look like the crops had not have failed? People who appear to be on power are usually powerless to change anything, and are often also unaware of what is really going on (or at least the extent of the problem). During history, rulers have often been intentionally kept ignorant, as in the case of Potemkin Villages. And when they are not, they have little incentive to actually inform themselves. This is true even today and in relatively free countries: in his big speech, the US president Joe Biden said that almost all Americans have been vaccinated against COVID-19 (354 million of them), when, in fact, less than half of them have been, due to logistical problems and vaccine hesitancy. He was arguably less informed about the issue than an average person is, so no wonder he cannot even begin to solve the problem. Clearly, world leaders of today are mostly just as ignorant as Hui Jin when he said "If they have no rice, let them eat meat." or as the anonymous princess in the Jean-Jacques Rousseau's Confessions (often said to be Marie Antoinette, even though that is unlikely) who said "If they have no bread, let them eat cake.", and Mao was a rule rather than an exception when it comes to that. If the country you are governing had been struck by famine for decades, and there comes a biologist called Lysenko claiming to have a solution, and many (though not most of them) biologists agreed with him, there is a very good chance you would implement their policies much like Stalin and Mao did. When their country was plagued by the COVID-19 pandemic, an illness with, at that time, no known cure or prevention, which appeared to mostly be spread by asymptomatic individuals while being very deadly to elderly people and other people with low immunity, and there was a group of scientists claiming that lockdowns and mask mandates could curb the pandemic, the vast majority of governments implemented policies similar to those that those scientists were suggesting. Obviously, those policies did not turn out to be nearly as harmful as Lysenkoism turned out to be (though, you cannot deny those warnings early in the pandemic, that suicide spikes caused by lockdowns might outweight any possible protection against COVID-19 that lockdowns could provide, were reasonable, after all, it seems now that they turned out to be true at least for teenagers), but they are similarly poorly-designed experiments (we still do not know beyond reasonable doubt whether they work) everybody was forced to participate in. Really makes you wonder how are most people today, including most politicians, really different from Stalin and Mao, does not it? Are modern politicians simply in different situations, rather than being significantly more competent and well-intentioned? Clearly, if their country is in some situation which seems hopeless, and there comes a group of scientists claiming without good evidence to have a solution, modern politicians are willing to force everybody to participate in a poorly-designed experiment to test whether that solution works. Yet, people seem to be obsessed with who is in power, as if that was likely to make a difference. The Croatian ex-prime-minister Ivo Sanader has been serving a sentence in Remetinec jail since 2012 for the abuse of power, and most people (at least those who have not been enough brainwashed by the right-wing propaganda to think the things he was convicted of did not actaully happen; I have asked a Quora question about that) think that happened only because we chose the wrong party at the election and that him ending up in jail is justice. In reality, justice would be if the society is structured so that such things cannot happen, and somebody else would have probably done the same if they were in their shoes. Restricting the government so it can do no harm is way more important than enabling it to do something good by forcing people to do things against their will. Such a paradigm shift in thinking, that people stop worrying about who is on power, and start worrying about what incentives people on power actually have, is hard to accomplish.
Even when people indeed are thinking about incentives, which is closer to the right way to think about political philosophy, they are often replacing real-world governments with something imaginary. They are often doing the same mistake as Thomas Hobbes did when he said an absolute ruler has an incentive to rule wisely because he can get more tax money if the society he is ruling is prosperous. That is extremely detached from reality: absolute rulers have an incentive not to rule wisely (poor peasants not making good revolutionaries, absolute rulers often being threatened by other people in the government that they will kill them if they does not kill their political opponents...) and often do not even have the ability to rule wisely (they are being actively misled about what is going on in the country by Potemkins in the government, and, more generally, social sciences are not yet advanced enough to tell rulers how to rule wisely).

What happened to me so that I became a libertarian? Well, I realized that the government-backed-up pseudosciences destroyed my childhood and teenage years. After my parents got bitterly divorced, somebody from the social security (and I am quite sure I know exactly who, but I won't name them here) made up a story that my father was a rapist and that I was a witness. Since they were in the government, many people believed them back then, including my mother. Both my parents lost their jobs and gave all the money I was supposed to start my life with to lawyers. That story was well-known, and nobody wanted to be a friend with me. I was lonely (thankfully, I am an only child, so I didn't have to share this little money my parents were able to spend on me with my siblings), and I became a part of a group of vandals and alcoholics. Additionally, my mother ended up in jail for a year (you can see excerpts from a letter I wrote to her back then). Government might steal money from my fellow citizens and give it to me in compensation, but it cannot give me my childhood and teenage years back. Even today, I sometimes get asked whether there is some truth to that story about my father. Uncomfortable, I answer that there isn't, but that that story, because the government got involved, had very real and devastating consequences. I am no longer an alcoholic and a vandal, and I am relatively respected among the people who know me. But to prevent other people from getting into such situations, I want to send a message: "Don't ascribe superpowers to the people in your government." That means don't believe ridiculous conspiracy theories, but also don't believe that the government can do miracles to protect us.

UPDATE on 14/07/2019: I've made a thread about libertarianism on a Latin forum, to see what people educated in history and social sciences think about it. You can see it here. In case that website ever goes down, here is that short essay in Latin I posted there:
Quid cogitatis de anarchismo? Ego anarchista sum, ego cogito melius esse, si imperia et leges non essent. Ego non video, quomodo possint bonae leges existere? Quomodo possint leges imperiaque societatem protegere? Consideretis: Nemo, qui non insanus est, vult aliquem occidere. Et militia venit solummodo postquam insanus homo occidat aliquem. Et tunc militia sinit eum insanum hominem in carcerem. Carcer non est (et probabiliter non potest esse) locus ubi is insanus homo sanus futurus est, carcer locus est ubi is plus insanus factus erit. Ergo, is insanus homo, qui suae insanitatis causa aliquem occidit, insanior revertetur in societatem.
Securitas, quae nobis data a militia est, falsa est. In saeculis historiae, etsi custodes et equites omnes spectabant et custodiebant, non poteras, viis in urbibus iens, securus a latronibus esse.
Et de rebus oeconomicis... Linguae videntur esse sine imperiis posse. Si linguae sine imperiis possunt esse, cur oeconomia non possit?
Et de rebus bellorum... Paene omnia bella horum temporum pugnae sunt, ut omnia bella cessent. Sed bella numquam bella inhibere succedent. Et tela solummodo raris temporibus veniunt ubi debentur, arma bonorum hominum saepe veniunt in malas manus.
Civitates amant falsam securitatem, quod leges et imperia dant eis. Difficile pugnare contra ei est. Multi homines censent libertatem civitates oeconomice parum strenuas facere, et quod libertas, quodam modo, facit homines res, quae non rationales sunt, facere. Id est cur habebamus Fascismum, Communismum et servos. Sed possumus sperare numerum eorum hominum, qui libertatem non amant, minorem in futuro esse.

UPDATE on 22/09/2019: I've just posted a YouTube video about pseudoscience in American politics. If you can't open it, you can perhaps try to open a low-quality MP4 file hosted on this server (it can be opened on almost any platform using VLC Media Player). Failing to do even that, you can probably download the MP3 audio.

UPDATE on 20/10/2019: I've just posted a YouTube video about libertarian philosophy in Latin. If you can't open it, try this and, if that also fails, download just the audio here. I've also opened a Reddit thread to discuss that video.

UPDATE on 08/02/2020: I've posted a YouTube video explaining why I think that, if you support free trade and free movement, you can't also support immigration restriction. If you can't open it, try to download the MP4 file.

UPDATE on 23/02/2020: I've translated the lyrics a song called E Moj Plavi (MP4) into English, which seems to express some libertarian ideas. ( UPDATE: I received a message from somebody claiming to be Đorđe Balašević about how my translation is offensive and asking me to delete all copies of it as soon as possible, or else he is going to make a lawsuit against me. While I find it just as believable it wasn't real Đorđe Balašević, but somebody who tries to shut him up, the risk of getting into such lawsuits is rather high. If it is him, it is sad that a singer who writes and sings anti-police songs will sue somebody for offensive speech, because it shows he does not actually believe what he preaches. )

UPDATE on 03/10/2020: I've translated a song against nuclear weapons into Croatian. You can see it on YouTube here. If you have trouble opening it, try downloading this MP4 and opening it in VLC media player (or something like that).

UPDATE on 24/07/2021: I have made a diagram explaining why vaccines work, and mask mandates probably do not:

Here is a quick explanation as to why gun control probably does not work:
Why gun control (probably) does not work?
What people think the law says: Let's ban guns which tend to be used in mass shootings to make it harder for criminals to acquire them.
What the law is actually saying: Let's ban assault weapons (automated guns that may actually come useful in self-defense situation when every second counts), while leaving the guns that are actually used in mass shootings legal. And let's make it illegal for mentally ill people to have any guns (never mind mentally ill people are also more likely to be the victims). Who cares about the constitution and privacy of medical information?
Mass shooters: *They tend to get weapons they are using illegally anyway.*
Meanwhile, the actual problem of mental illness because of which people engage in such crimes remains unaddressed.
Here is a quick explanation as to why governments probably cannot help end pandemics:
How can a government end a pandemic?
Lie to people Tell people the truth
The government of Neatherlands: As soon as you get vaccinated with the J&J vaccine, you can safely be "dancing with Janssen".
Young people: *Do what they are being told.*
*COVID-19 cases spike, and will presumably be followed by a (relatively small compared to 2020 at the same time) spike in deaths.*
Anti-vaxxers: See? We have told you that vaccines do not work! Neatherlands has a high vaccination rate, yet cases are spiking there. Government is lying about how effective the vaccine is, so how can we trust them they are even safe?
*Many people refuse to get vaccinated.*
Croatian government: Do not go dancing immediately after you get vaccinated. And do not drink alcohol soon after getting the vaccine, it can make the side-effects of vaccination worse. Vaccines only start working after 2 weeks, and in some people only after 4 weeks. And even then, it is hardly responsible to go dancing as long as the virus is circulating around. Getting vaccinated decreases your chance of spreading COVID-19 if you catch it only by around 45%, and there are still many uvaccinated vulnerable people around. Furthermore, vaccines do not exactly reduce the chance of vaccinated 75-year-olds dying from COVID-19 down to zero, they are about as immune as unvaccinated 50-year-olds are.
Young people: (wrongly thinking) Ah, who cares then? Who cares that there is this pandemic in the first place? I am very unlikely to get seriously ill from it. And who cares that the economy is suffering? At least the air is cleaner.
*Vaccination rates remain low.*
And, by the way, it is hard to tell whether "As soon as we all get vaccinated, we can return to normal." is true. The answer to that depends on the variables we cannot reliably estimate, such as the R0 of the new variants and how much vaccination protects against infections (that is, how common are asymptomatic breakthrough infections, which, without a doubt, usually go undetected). It is quite possible that herd immunity against COVID-19 is impossible and that everybody, including immunocompromised for which vaccines do not work, will sooner or later get infected, and that massive vaccination is, at best, buying time for new effective treatments to be discovered. Also, as the CNN puts it: "And it's hard to be confident that the virus is not infecting millions of fully vaccinated people and perhaps evolving in their bodies under pressure from a vaccinated immune system -- a scenario that is unlikely but that could, in theory, give rise to new vaccine-impervious variants." (this has happened once, in case of a cancer-causing virus in chicken called Marek's disease - it has, much like HIV, evolved the ability to shut down the immune system before it has a chance to act, arguably pressured into doing that by too many chickens being immune to it due to vaccination). If some mutation to COVID-19 could enable it to shut down the immune system (It is indeed very unlikely, but how can you prove that is not true?), massive vaccination is actually decreasing the amount of time we have to find effective treatments, rather than increasing it. To justify the huge government policy of forced vaccination, don't you need to show the horrible consequences are impossible, rather than just unlikely? The consequences of you getting vaccinated are easy to tell: you are unlikely to have symptoms of COVID-19 if infected with current variants, and most likely future variants as well. The consequences of policies intended to force everybody to get vaccinated are very hard to predict.

UPDATE on 27/08/2021: I think I have figured out a nice response in case somebody on an Internet forum asks you to stop talking about politics. Say to them "OK, then, let's talk only about idiotic things. You know, Aristotle called all things not related to politics 'idiotic'.". The joke is in that the word "ιδιωτης", which Aristotle did indeed use to mean "things not related to politics", meant "private" or "one's own" in Ancient Greek, it is just that the word has changed its meaning over centuries drastically.

UPDATE on 16/02/2022: Here is an interesting conversation about gun control I got myself into:
The vast majority of people would not die or get seriously ill from COVID. That does not mean one should not get vaccinated against it. Similarly, the vast majority of people will never find themselves in a situation in which a gun would help, but that does not mean one should not get one as a precaution.
get one
before you get one - pass a pyschology test, safety test, licensing, insurance and registration etcetcetc
And do you take responsibility if somebody is murdered because they cannot defend themselves because they failed the psychological test? It is not a stretch to imagine that happens. A marijuana user will probably not pass the psychological test, but they may very well need a gun for self-defence, for example.
Youre really flexible.
You must be a gymnist.
I take it to mean you have no answer to that. As somebody who has suffered from mental illnesses my whole life, I find the suggestion that I have no right to self-defense just because of that very offensive.
there is no answer for such a stupid request.
if you want one i can piece something together

you have right to defend yourself.
you got 2 arms 2 legs.

does the mayor take personal responsibility if you personally get attacked?
not unless crime is so rampant in your neighbourhood.
feel free to sue the mayor.

but for the 100s of people you meet everyday, do they have the right to safety?
can we trust the gov't has done everything reasonable in their power to ensure to know that you, a possibly mentally disturbed person, does not have a gun?

why does a mental person need a gun for the off chance they're attacked?
are you so paranoid that someone's out to get you?
you believe the earth is flat and there's gov't conspiracy against you?

ya... no sorry i'm pretty sure the risk to others outweighs the risk to you.
No, I am not a Flat-Earther, nor do I think there is a massive conspiracy against me. I simply think laws that prevent the prevention of a crime are bad laws and that people who want such laws are partly responsible for the crimes they cause, if I was not clear enough. Laws that require psychological tests for somebody to own a gun can easily prevent the prevention of a violent crime, since mentally ill people are often victims of violent crime. They are taking away guns from those who are more likely to be victims of violent crime. If passing such a law is not irresponsible, I do not know what is.
It is amazing to me that the people on the Flat Earth Society forum tend to be rather anti-gun. I'd expect Flat-Earthers to be anti-government and therefore pro-gun, but apparently I was wrong about that. Guns often save lives. Every study about that that I am aware of shows that guns save at least as many lives per year as they take, if not a lot more. As such, any gun control policy is risky at best. It is amazing to me just how certain gun control advocates are that their policy would save more lives than it takes, and not only that, but also being utterly incapable of accepting any responsibility for the harm it might cause.

UPDATE on 28/07/2022: I have made yet another YouTube video about anarchism (MP4).

UPDATE on 01/12/2022: My anarcho-capitalist comment on r/WhitePeopleTwitter received an unexpected number of upvotes:

UPDATE on 08/12/2022: People on AtheistForums insist that Irish Potato Famine is caused by capitalism (and that Great Chinese Famine had nothing to do with communism):

How can anybody think that way is truly beyond me. In my opinion, the Irish Potato Famine may be classified as an intentional genocidal policy, similar to Holodomor.

UPDATE on 08/12/2022: People on AtheistForums insist that Great Chinese Famine had nothing to do with communism:

Once again, how anybody can think that way is beyond me. I am not saying communism inevitably leads to something like Great Chinese Famine. But it's hard to imagine how pseudoscience such as Lysenkoism could have such disasterous consequences in a capitalist society.

UPDATE on 25/12/2022: I have written an essay specifically about the lessons I believe we should have learned from the COVID-19 pandemic.
