do you know where your food comes from, are you aware the world resources are not infinite.

Or do I need to explain why everyone can't own their own house on the beach because there's is only so much costline(not to mention the environmental coats)

Explain how early human society didn't start with anarchy exactly?...how exactly do you expect an anarchist group to survive if you and the other guys from other group both need food but there is barely enough to feed one group.

Do that and replace food by whatever you want
