I think its just human nature dude.
there's no such thing as human nature in the way that youre referring to it fyi. that whole notion is basically a conservative reflex of people who'd rather not think too hard about things and essentially strips people/communities of any sort of agency in the development of civilization.
why bother analyzing history, or putting any effort into making social change, when you can just reinforce the status quo by attributing current social behaviors and institutions to some nebulous static axiom that basically means whatever you want????
"of course we have slaves that's just human nature"
"of course we worship the gods/trees/idols thats just human nature"
"of course people play sports thats just human nature"
"of course there's nation-states, that's just human nature"
"of course there's a king thats human nature"
etc etc etc
