I had a debate with a friend the other day.
He said that an anarchist society would not last very long without being conquered by some government.
I used Stefan's arguments: that governments have no incentive to conquer a society that has no tax structure, etc.
He basically said: "There's been a number of anarchist societies. If what you said is true, then how come not a single one of them could resist being taken over by governments? there aren't any anarchist societies left."
What would be a good answer to this?
