You don't get it.
The type of men who play VR waifu games... what they want is a wife. They want sex too, but that's secondary.
The woman in your webm is a whore who have already beem penetrated by other men.
She's a cum dumbster. No man in his sane mind would marry her.
VR girls make for a nice replacement in the short term for the extremely rare virgin traditional woman who wants to be a housewife.
