First off, like I mentioned earlier, I'd imagine most consumers would prefer to go to a legit business that has regular STD testing rather than getting an illegitimate hooker off the street.
Second, as in the case of the Netherlands, illegal immigrants can work as prostitutes and receive the same benefits as a legal citizen. I think the US should have the same mentality but illegal immigrants and work is another topic comrade.
Third, you're really not making any arguments to back up as to why you think illegal prostitution slows down the spread of aids and why legal prostitution increases it.
Sure, I can agree that some people would choose to remain prostitutes illegally, but this does not prove any points. It seems as if you’re agreeing that legal, regulated prostitution would decrease the spread of STDs, but there would still be illegal hookers. Well, that’s true, but as I mentioned, most consumers would spend their money at an established place of business that regulates STD testing.
As of right now (besides some parts of Nevada) there is NO required STD testing, none, zero, nada and yet millions of people pay for sex. On one hand you have zero testing, on the other you have testing. Which one is safer?
