> Before civilization, it used to be that the most violent person in the group could simply take whatever they wanted.
My understanding is that in hunter-gatherer societies, that is not the case and they were (and are) quite egalitarian. E.g. (https://www.psychologytoday.com/gb/blog/freedom-learn/201105...):
>The writings of anthropologists make it clear that hunter-gatherers were not passively egalitarian; they were actively so. Indeed, in the words of anthropologist Richard Lee, they were fiercely egalitarian.[2] They would not tolerate anyone's boasting, or putting on airs, or trying to lord it over others. Their first line of defense was ridicule. If anyone—especially some young man—attempted to act better than others or failed to show proper humility in daily life, the rest of the group, especially the elders, would make fun of that person until proper humility was shown.
>One regular practice of the group that Lee studied was that of "insulting the meat." Whenever a hunter brought back a fat antelope or other prized game item to be shared with the band, the hunter had to express proper humility by talking about how skinny and worthless it was. If he failed to do that (which happened rarely), others would do it for him and make fun of him in the process. When Lee asked one of the elders of the group about this practice, the response he received was the following: "When a young man kills much meat, he comes to think of himself as a big man, and he thinks of the rest of us as his inferiors. We can't accept this. We refuse one who boasts, for someday his pride will make him kill somebody. So we always speak of his meat as worthless. In this way, we cool his heart and make him gentle."
