This is the crux of the Civilization Problem Male and female biology is optimized for survival during tribal hunter-gatherer times. The traits which ensures both your offspring and the collective tribe survive are the traits that are passed down through evolution For men sperm is cheap. Impregnating a woman has little cost. There is little drawback to simply having sex with as many women as possible as far as survival goes For women pregnancy is extremely expensive. Impregnation by the wrong man means weak sons who do not themselves reproduce, and a tribe unfit to combat rival tribes Because a single man can impregnate many women, women have no need to procreate with their "looks match". They can all get impregnated by the most capable in their tribe - the strongest, the most capable of violence, the one with the most status and resources It's then no surprise that height, muscles, ability to fight, status and wealth are all female attraction triggers today But that model doesn't permit tribes to grow. Most men do not get to procreate, and have little incentive to be productive, while all the top-tier men get most of the women The solution is simply chaining the two together When men can ONLY get sex through marriage, and women CANNOT have sex outside of it, you chain the productive sacrificial nature of men with the development of families Most men get to reproduce, creating new productivity units for the tribe. Tribe gets stronger. More things are built. Survival becomes easier From here civilization forms. Quite literally the building blocks Feminism and hookup culture are the metaphorical equivalent to setting off C4 charges at the base of a building, that building being civilization itself One way or another we're going to eventually go back to the only model that has ever worked for humans because our DNA has not changed much over the years
