What is """objective""" desirability.
Good question, I can't give you a proper answer for that.
Best I can say is becoming god and applying some ruleset such that each person ends up with their looksmatch.
Obviously I'm talking about desirability by the sex you find desirable.
We've already lost if we start from here because although men find women in general desirable, women only find like 20% of men desirable, to the point where women see ugly men like how a straight man would see another man.
Quality of other forms are not relevant to this dynamic.
They are because it has to be a 2 way street to ensure sustainability.
The market is so heavily in favor of women this is the situation that makes the most sense.
It really doesn't no, unless you want the market to favor women heavily at the expense of men, which kind of invalidates your premises as well.
The man can have sex with her, still.
Like no though because she isn't even attracted to ugly men, the premises would be violated.
