I would love to think it was possible for prostitution to be made illegal, but I don't see how it will ever be eradicated.
Sex genuinely is a recreational activity for men, in every sense of the notion. It's not for women because it carries the potentially extremely far-reaching ramifications of producing a child. The playing field couldn't be less level, and that's never going to change.
Pregnancy and its far-reaching ramifications is simply is not something men - especially punters - need worry their little heads about. So certain men will always avail of their services.
They don't see what I, and presumably other feminists, see - that they're buying someone's consent, who would otherwise not be in the slightest bit willing to give it, i.e. they're essentially raping someone.
They seem themselves as indulging in a fair exchange.
No matter how much of a sea change there is in prostitute-user's attitudes, sex, for them, is nothing more or less than an enjoyable pass-time, that they see plenty of women willing to sell to them.
