EXACTLY! Which is all I ever say - that by noting that the current state of inequality and social stratification is not timeless or universal, we understand that it is not inevitable and we are better equipped to take the best aspects of other social systems and incorporate them into our own in the present day. Pretty much every story I've written about the contrasts between patriarchy and more egalitarian systems ends with a sentence or two which says exactly that. Here are 3 such quotes from 3 different stories:

"Quite obviously, we can never go back to widespread leaderless egalitarian societies, but there are still things that we can learn from that sort of social structure."

"Agriculture and the patriarchal dominance hierarchies that came with it allowed what we would call civilization to be built, but it also ushered in a time of social stratification that we have never recovered from. Although we can never return to the hunter-gather lifestyle en masse, the fact that inequality is such a recent human development gives me hope that we can find our way towards greater egalitarianism. After all, we’ve only had inequality for 3% of human history. Surely there are things we can learn from our pre-patriarchal ancestors about how to take better care of each other. I think that accepting that patriarchy is not timeless and inevitable is a good place to start."

"Egalitarianism is not about being a “noble savage” — it is a vital intentional strategy that was fundamental to human survival. It is not about Utopianism or some sort of “perfect culture” either and I’m not advocating that we try to become like indigenous cultures in every way, since that is hardly possible or even necessarily desirable in the modern Western world."
