So, what would happen if men didn't patronize places where sex-trafficking happens?

3. Well, don't those who would mostly already do that?

The need for sexual services is paradoxically increasing with "women's lib," not decreasing. Some men always needed, or just wanted, them, but today many who very reasonably expected to grow up to participate in the American dream are finding themselves involuntarily celibate.

Being able to purchase legal, clean and decent sex won't fulfill that dream, of course, but men should be able to seek out these services morally and acceptably respectably, without having to wonder if propositioning a nice looking but clearly professional female on a bar stool could somehow be contributing to trafficking atrocities.

That can't happen where all sex trade is illegal and laws poorly enforced, of course.

As for those who do patronize places where trafficked flesh is offered, imo, they should be prosecuted and sentenced to serious prison time when proven guilty of crimes, and this hardly impossible to achieve. We'd never see all customers take the self-service vow, but we could see almost all with nowhere to go but their own couches.
