Just because jealousy is a human tendency doesn't mean that there aren't all kinds of cultures all over the world that do not practice sexual monogamy even though they have something called "marriage." It also says nothing about pre-patriarchal cooperative breeding (rather than nuclear families provided for by the man as you have asserted). And it really, really says nothing about the fact that patriarchy is demonstrably only 6-9 K years old, which is how this "discussion" began.
And why on earth would you jump to the conclusion that I don't support sexual freedom for men? What do you think was happening with Paleolithic cooperative breeding - that only the women had more than one sex partner? That's just mind-boggling, but also indicative of why it makes no sense to try to talk about the facts with you because you do this kind of bizarre mental gymnastics that is essentially you puking your Id onto the page. I'm always happy to have in depth conversations and debates with people who are willing to actually engage with reality on some level.
Please do check out my other writing, including things in my publication Sensual: An Erotic Life, which is a sex-positive publication, supporting healthy, honest, respectful sexual freedom for all. I have a tab for my stories in the menu. I also have another publication called Inside of Elle Beau that has a menu tab for stories about sociologal and anthropological aspects of the kinds of things we've been talking about, as well as how the shift from egalitarianism to patriarchy impacts our culture today.
