I'm far from an expert in the issue, but I think that most people that support the legalization of prostitution don't support the legalization of human trafficking.

That's a really bad example because prostitution by itself is victimless crime. In fact, it's perfectly legal when money doesn't change hands! With gambling you have a winner and a loser, so all the other issues end up downstream necessarily whereas human trafficking (and other issues with sex work) is an enabling tool for criminals running prostitution operations.

The weirdest thing is that (paid) prostitution is completely legal as long as there's a camera involved and you distribute the recording.

Okay!

> worst aspect is the large amount of marketing and advertising these platforms receive

Virtually no one is advertising prostitution or human trafficking — certainly not to the degree that gambling is being advertised.

By extension, it seems we can agree prostitution and human trafficking are not nearly as severe a problem as gambling.
