A government is an organization which possesses a monopoly on violence in a given geographical are. They employ violence against people who do not act according to their laws, because supposedly they and their supporters want people to do as the law says. But, imagine a world where everyone actually followed the law. Such a world would be EXACTLY the same as one where the government did not exist because it would not be punishing anyone. Now I'm different, because I think that laws should be made to be broken and that certain people should be punished no matter what they do.
That's only correct if following the laws would still take place voluntarily without the threat of violence by government.
Laws, justice, and punishment are all outdated concepts. People would be better off if they were left in the past with all forms of tyranny.
