Prostitution has always been an outlet for men who are too unattractive physically or emotionally to score women on their own. Ironically these are also the types of men that, after being continually fucked by society that doesn't give two shits about them, go on to build bombs and shoot up schools.
Think of most of the angry, shut-in, potentially explosive dudes you know. How many of them are getting laid? Maybe 10% if they are lucky (and most of the time, it's with an unattractive woman). By drying up the supply of pussy for these men, you are making it harder for them to cope and more dangerous to society. It is a necessary evil and to attempt to make it illegal is, at best, ignoring reality, and at worst, putting the lives of innocent people in potential danger.
