I believe that is general true with all black markets. Legislating morality doesn't make the activity stop it pushes it underground where criminals can capitalize on the black market. Same with weed. Sunlight is the best disinfectant but sunlight doesn't go underground. If the market is above ground it might actually make stopping those violating the law easier. Never mind also, in this case, improving health by mandating things like screenings and protection.
