I absolutely insist on living in a society that permits people, including me, to get naked or have sex for money, or for whatever other reason they like. That's a preposterous question to me.

Obviously, I would prefer to live in a society where no one needs to do work that does not align with their moral or ethical beliefs. Though I have never heard of such a society.

I expect some people find it enjoyable or empowering. Why should we take that away from them?

If people are only doing it because they can't make money elsewhere, maybe fix that problem instead of taking their only income away from them.

Permits? Bear in mind that many people just like getting naked online for an appreciative audience for free. Should that be permitted? This creeps toward a puritanical perspective and is just as claustrophobic. Sometimes the line between preventing financial incentive and preventing immorality blurs.
