Prostitution is not exactly a reputable business over there either, even though the girls actually have to pay taxes on their earnings, and submit to regular health check ups. Even the prostitutes have universal healthcare over there. The benefit of legal prostitution is obvious: tax income for the city, healthier girls, and safety. In Amsterdam, each girl has an alarm button next to her bed that she can press if one of her "customers" tries to rape or hurt her. The police will arrive within minutes and protect the girl from harm.
