I'm not sure prostitution could ever become legal because it's selling one's body, kind of like slavery? One could argue that a construction worker is selling one's body but that's actually selling one's labor the body does whereas sex is part of the body, not something separate. Even legal, there would still be pimps/mesdames and "organization" and the whole crime element I think. I think it would be harder to protect children from being prostituted by their parents if it were legal.

I think the number of prostitutes that are prostitutes because that's what they want for their lives is extremely small. I don't think legalizing prostitution would help the poverty/desperation/drug problems associated with the act?
