I think sadly it's because this is sooo normalized for the younger generation... I hear rather constantly (though am still shocked every time) about young women I meet selling photos on OF, having sugar daddies, doing 'sex work', selling nudes/sex to random rich men they meet, going to sex parties, etc. They've grown up thinking this is a perfectly normal and in fact smart way to make money, so naturally men have come to believe this as well, as young women (or bots) offer it to them constantly online and in real life as well.
