Are you talking about prostitution? That's a sexual marketplace. This article isn't talking about people buying and selling sexual encounters. People deciding to have sex with one another doesn't mean that there exists any sort of bartering or trade. The overwhelming majority of sex is because it feels good and all people involved want to feel good. Living in your parent's basement isn't sexy, but not because one isn't rich, but because it indicates that one cannot make it in the real world. Kids live with their parents and no one wants to have a relationship with someone stuck in a child's mentality. Or even remotely resembling it. And you completely ignore homosexuality and the fact that now, more than in the past, is it possible for one to come out and not be eviscerated. A likely explaination of the same data is that more women are having sex with one another.
