You are definitely right on this one. As long as it remains illegal it must be prosecuted, for the sake of law and order.
It is not exactly a clean business now. Maybe a car sales isn't a good comparison, but why would it be different from a cabby? A service is being provided. The gov't should regulate safety, because who else will? If you say that they screwed up medical care, fine, but who cares if they screw up whoring? Cigarettes, among other things, are considered unethical today, yet they are legally sold by good, honest people, and have reasonable quality control.
No, I am not trolling. I really do think like this, and will continue to do so until someone fixes me.
Edit: I can't separate
