I never said it should be seen as regular work. Decriminalization just means you can't go to jail for it. However, this isn't regular work. If this is a consenting adult, then it shouldn't matter and remember they are paying for sex not really the person. The point is, that there should be a way out for the sex worker.In my opinion, s*x work should not be seen as regular work. You simply can not buy someone, even for a x amount of time to use them and change to another term to justify it. Even if it's "consensual", it's still exploitation, as simple as that.
Your moral/ethical judgement, should stand beyond what law and constitution permits you.
