They were actively staving them off. We know this because of the vast amounts of evidence from both modern egalitarian groups such as hunter-gatherer tribes as well as quantities of other evidence from history. One example of this I've already just cited to you about the people who wanted to be on local councils and how they were rigorously vetted, had to fast and undergo trials or other sorts to ensure that they were interested in serving the group, not in creating a hierarchy that they were at the top of.

Enforced egalitarianism was actively undertaken and enforced. It wasn't just a bunch of noble savages who hadn't yet thought up dominating others. Many anthropologists believe that this active rejection of the sorts of dominance hierarchies which are natural to other primates was a central element of human evolution. It's why our strain of proto-humans survived and others did not - because this enforced egalitarianism was a primary survivial strategy.

I think we've hit upon the crux here about your problem with the word patriarchy. You assume it indicates evil intention and I don't. It's a social system that arose naturally due in part to changing cultural and economic conditions in conjunction with "greed, jealousy, envy, sloth, etc." which manifested into a dominance-based social system which just so happened to have men at the top of the pyramid and known paternity as a central aspect - making it appropriately named Patriarchy. The fact that the people in power then went on to solidify and ensure the continuation of that traditional power via creating structures and laws upheld by violence, coercion and the threat of violence does speak to serious human flaws which some might even characterize as ill intent, but that's a slightly different thing then the question of how did this patriarchy arise in the first place. For 97% of human history paternity did not matter and women were not controlled and subjugated by men. Maybe you don't like the term subjugated but it is factually and historically accurate and was appropriate up until about 60 years ago when hundreds of laws and thousands of cultural beliefs that imagined women (and Blacks) as fundamentally and inherently less began to be actively challenged.

I've already completely and utterly proved that nature and nurture are not the same things but since you refuse to acknowledge that, I suggest we agree to disagree on that one and put it to the side.
