But even then "age gap" itself is modern concept. In the past people valued women for fertility. They wanted to know that the man would provide and treat her right. It didn't matter if he was 15 or 25.
This goes to show that your mind has been totally wrapped because of modern AoC laws.
The reason it's natural for normal men to prefer women who display maturity is because as a species our children require a lot of investment, it's over a decade to even reach puberty. While a man is out doing other shit, their partner is going to be the one responsible for rearing one's child. If you have a dippy 15 year old who takes terrible care of herself while pregnant and accidentally puts drain cleaner in your kid's sippy cup or lets it get eaten by a wild dog because they're weak and/or stupid, that'll have major reproductive consequences. The loss in fertility caused by waiting until a woman is, say, in their mid 20s is vastly outstripped by what they gain in fitness as a mother.
The reason it's natural for other people to tell you to keep your hands off teenagers is specifically because the people who target them are consistently either deadbeats (those who can't care for a family) or extreme narcissists (those who won't).
If AOC laws didn't exist then it would be the family controlling access. That's why when older men and younger women were paired, it was traditionally always through arranged marriages. However if families/communities are unable to address a given undesirable behavior (which becomes increasingly difficult as population density and community fragmentation increases) then people delegate that responsibility to the government.
And yeah, you're right, there are stupid chicks who never mature past their teens anyways, but the overriding point is that society has nothing to gain by lowering the age of consent.
That's why your obsession with the law itself is so weird and faggy, because if you said "The law is stupid, I'm going to go take over a small nation by force and there age of consent is going to be 14" you'd be delusional, but at least it would seem less pathetic in spirit.
But your conceit is "I'm going to sit here whining and trying to make arguments as to why you're stupid if you don't think I should be able to screw 14 year olds then everyone will pat me on the head and let me screw 14 year olds pretty please?" so not only are you an obsessive creep, but you're also a pussy and a whiny indolent retard.
