Surely that's more a lack of proper regulations and enforcement. Things designed to keep safety and standards instead of punishment and determent.

Elaborating: If there is sufficient /convenient/, legal, not over-priced, service for the clients that clearly do exist then underground (criminal) fulfillment is much less profitable. Making onerous (for no good reason) regulations are one form of increasing the price of legal services and thus making it more profitable for unwanted fulfillment to occur.
