No tax in the wild? In my view, sure there was: you get water and share it, the other guy hunts and shares it. The fact no centralised system existed does not mean no tax on the community was levied in some way.
==Taxes in that system would be more like 10 men who did not hunt or gather demanded you give them food and water or they would beat your face in.==
This seems a little dramatic. Are the 10 men demanding food and water also building roads, cleaning the water, removing waste, educating children, protecting collective assets, or any of the other things that Governments do with collective taxes? If not, the analogy falls apart.
Once the hunter demands water for meat it becomes an exchange, and is the basis of our capitalist society.
