Does legalized prostitution solve all the problems inherent in the errr........ industry? Well.....No, probably not.
But having said that, it is better to monitor something out in the open than to drive it underground in some scenarios.
If men and women are paid to have sex in front of a camera which is totally legal, then why aren't men and women allowed to be paid to have sex off camera? (I know most prostitutes are probably women, but I'm sure there's a few men in there somewhere.) What's the big leap between the porn industry and legal brothels?
Hell what's the big leap between higher up "escorts" and prostitutes? (Don't try that "they don't have sex" BS, it's practically common knowledge that escorts are just fancier prostitutes.)
If it is under the control of Government regulation, then theoretically at least, it would be easier to ascertain who is consenting, who is coerced and who is underage. And then hopefully save (at least a few) women from the clutches of unscrupulous pimps.
Someone mentioned before they were angry at watching COPS when they just arrested the hooker and I happen to agree. If said hooker is on drugs or under the thumb of a menacing pimp, all the coppers are doing is causing undue stress to a likely frightened/abused woman. If she is viewed as nothing more than a criminal under the law, then how can she get help if she needs it?
Prostitution is legalized where I live. I distinctly recall in High School everyone knew of the brothel a couple of blocks down the road from the school. And many a story went around the playground about the lads who tried their luck at the establishment. (Alas, unless they were particularly older looking, not many had much success. In spite of their tall tales of sexual prowess.) Because it was regulated, the "type of John" was also under a bit more scrutiny. Did that mean all the workers were completely safe? Well, no. But it did mean that if someone was out of line, they could just call the coppers without fear of being locked up themselves.
Hell sex workers even have their very own Union and I see them campaigning for more protection under the law and more rights as employees every now and then. Which I support.
Would I encourage anyone I know to go into any sort of sex industry? No. But some women might like that particular profession, so I'm not going to stand their way. And so if they are involved, I'd prefer them to be in a position where the police could legally offer them protection and regulate their employers, instead of just chucking them in the clink if they happen to catch them unawares.
