I think there is a context where china's choice to make porn illegal is at the very least understandable. I also am sympathetic to the fact that the porn industry is rife with massive exploitation and human trafficking. Including children.

This guy above though is nuts. He has bad opinions about sex in general and doesn't understand that a consenting couple can post a video of themselves (even for money! Oh no!!)

Ultimately I think its fairly obvious that most sex work is done as a result of material circumstances. Like all labor, this makes sex work a kind of slavery. In order to root out the issue of women having to resort to sex work to feed their families (absolutely not a shameful thing to do by the way) we must address the material circumstances of the population. We should not be punitive with people who are trying to support themselves. We should be extremely punitive with pimps though, who are just human traffickers. With legal porn industry, obviously it must be regulated strictly with the wellbeing of the sex worker in mind.

After material conditions are addressed there will remain a subset of the population who still performs sex work, which would be just fine and good if they find that fulfilling. This is my opinion on sex work.
