Can you be specific about when, where and who was doing this?
Or are we just assuming that primitive societies didn't have hierarchies or violent social orders?
I mean, it is possible the first two humans ran into each other and said, "hey, let's trade and be friends" and then it was all downhill into statism from there.
But I am not sure we can assume that as being more likely than that the first two humans met, one raped the other and made the victim their slave.
Barter isn't necessarily a free market.
Maybe statism did evolve from free markets. Being very ignorant about that idea, I can suppose for now that it is possible. But if that's the case, then are you saying that statism is inevitable and not subject to future evolution, or are you saying that it's pointless to get back to free markets because they will just turn into statism anyway?
So you are saying free markets imply no hierarchies withing the voluntarism social structures and have no violence?
I see a no true Scotsman logical fallacy.
Humans are violent. If there is going to be human markets, there will be violence. Get over it.
