You're ignoring the existence of chieftains, little monarchs...

Those didn't exist before we stopped being nomadic tribes; those existed after the invention of the aforementioned plough, before we settled down in towns, cities, city-states, states and nations eventually. You're making my point here, for which I'm grateful :-)

But 10k years later you've got two of us arguing on the blockchain-powered website instead of worrying whether or not we'll please the local warlord ;-)

Warlords are indeed local, and always on the prowl for additional localities. With that I refer to the previous point ;-)
