I'm not against those who work for sex, but the idea to earn for a living doesn't seem nice. IMO, sex should be for 2 people (or more for others who prefer polyamory) who wants to be intimate/romantic with each other. My point is money should not be the purpose.
I approve. I think it should be legalized. I'm not sold on the libertarian view of complete decriminalization though. Capitalism is innately exploitative, and If it's not regulated to maintain workers' safety, and rights, then I'd expect working conditions to be just as bad if not worse for the laborers, which I think is a big reason why so many people want to keep it outlawed in the first place.
