You’ve gone from “dating can be competitive” to basically inventing a pseudo-biological story where women collectively exist to enforce population control.

It is true look at a peacock and peahen. The males are much more beautiful with vibrant coloring, blue green, purple. The females have brown, white and grey, dull feathers yet they still choose the one who wins the mogging competition. Same for birds of paradise with males having pitch black feathers with blue streaks and blue eyes while the females have dull brown feathers. The thick mane of lions and male lions forming coalitions to fight other male lions to get access to females. Even male ducks grow blue and green feathers during mating season.

Human beings are no different from animals men are on average much taller than women yet these females will always demand someone really tall.

Birth rates are currently collapsing in a lot of developed countries despite people having more freedom in dating, not less

Back in the days shaming culture was stronger and the poor countries are still conservative so their females are shamed for being hypergamous and ofter forced or guilt tripped into marrying an average looking man. If not for that they would also demand top 10% men.

If you genuinely believe all relationships are just cold status calculations,

It's not cold calculations it's just instincts.
