Good points TT. However, consider that a cops job in society is to essentially take out the trash, and deal with the bad element, so that folks don't have to. Most folks just want to be left alone, go to their jobs, and sleep at night without worrying about their property and family. Therefore, folks pay their taxes, to pay the police to do the job they would rather not do. In your example, there would be extreme Darwinism. The strong would survive, the weak would die off. I agree it could be a functioning system, but a very tough world to live in for most folks.
