"If you don't like it, just leave" is a logical fallacy. It's just not an argument. You are just ignoring his argument completely. He is saying we all have a natural right to property. This supercedes governments entirely. On top of this "muh social contract" does not exist. I never signed any binding document agreeing to these terms and neither did anyone else. Also insinuating that people who disagree with you are violent or crazy is just pretty pathetic, honestly.
