If anything, our evolutionary history indicates a promiscuous lifestyle with everyone having sex with everyone else and post-spermatic competition.
Sorry, repeating the same point won't make it any more true. Still haven't seen any evidence for this stat, only American stereotypes.
It's hard to track people's sex lives for obvious logistical/ethical reasons, but the most accurate study I've read on that was about teenagers in a high-school in a small rural town, so a closed environment that's easy to control. Forgot the link, will track it down if you're interested. But basically the "sex encounter" graph was fairly evenly spread and evenly balanced between men and women. Sure enough there were "clusters" but they were engaged with each other, not monopolizing 80% of everyone.
As it turns out, if your social circle is made up of sociosexually unrestricted people, everyone involved is going to have lots of sex. If it's made up of restricted people, few people are going to have encounters. But one person or two keeping all women in a sort of "serial monogamous schedule" while they do liteally nothing else? That doesn't make sense and I've never seen it happen, nor have I read any actual scientific study about this.
If that were true people wouldn't automatically switch to love marriage when uncoerced. My experience of dating people from cultures where arranged marriage is still a (dwindling) thing tells me that no, they absolutely wouldn't go back to the days where it was prevalent.
"But they learned to make do and be happy in the end!" is not an argument. It can be used to justify literally any practice, because people always strive to be happy even in the worst conditions.
Seriously, what's with people wanting to coerce other people's romantic lives? When did we switch from "live and let live" to "the state should give me a girlfriend"?
But seriously, think about the implications of these numbers: do 8 women just patiently wait in line for 2 men, doing literally nothing in the meantime while the remaining 8 men just stare at their feet or something? Is it something that people think actually happens in real life?
