If you want to go far enough back that we use theory
Then we can say prehistoric nomadic humans still had fights with other clans and territorial disputes because our genetic ancestors (chimps/monkeys/apes) also have those
And if you were there with a gun, would you be able to dominate them? If so then you are able to put power over people without a power structure
it is not just farming land that is valuable, sometimes there are good fishing spots and etc in scarce regions. However those are far rarer situations and usually there is plenty of food for everyone, but hard times also happen and then most animals and humans practice mutual aid.
There is a good book about it, by Kropotkin, called Mutual aid. It isn’t long, I listened to the audio book.
Historically you are incorrect
If you don’t put power over someone else then someone comes in and puts it over you
The vehicle for change was just how easily that other person can get to you
You can go back to bronze age kings to demonstrate how what you said was false in all of recorded history
There is a good yt channel talking about egalitarian societies in prehistory called What is Politics

Territorial disputes where only common after agriculture in humans, because territory wasn’t as important before as mutual aid.
You can point to territorial disputes between non-agrarian humans to suggest otherwise
Hunting grounds and shelter were more important than mutual aid
You don’t even need to use humans, you can use other primates
