I think that the basic thesis here is fundamentally wrong, or at least it's clearly wrong sometimes. It's memed to death, but the anime girls these gooners get off to fundamentally don't look like human beings, which is made obvious by the fact that you can't actually coherently imagine one in the real world without either completely changing them or having an abomination on your hands.

"It's called art, sweaty"

In the loosest sense of the term, yes, but my point is that if you are able to make a really arousing cubist woman, calling it merely "an impossibly high standard" and not "some human-inspired thing that gets some people hard" is a confusion. Anime girls are just a more accessible version of that.

"why are you talking about anime when the gooners are mostly 'correcting' non-anime games?"

Because when you see how they correct them, it's clear that anime girls are a major reference point for them.

Like those artists that Miyazaki criticized, these people don't just have high standards, they are coming to prefer the non-human simulacra over humans, at least for their sex objects.
