When prostitution is illegal, they are not able to receive the protection of society and the police. They are not able (or are discouraged) from taking advantage of social welfare programs. We are taking an already vulnerable and preyed upon population and essentially throwing them to the wolves. Lastly, how does legitimizing sex trade increase gender inequality except perhaps by empowering women (who are in considerably higher demand in this respect)? I'm not seeing the problem in #2. Maybe you can help me.
