Indeed just having one region legalize skyrockets trafficking. Prices also go down, so prostitution becomes less attractive to locals as a way to make money which means foreigners in poor countries have to be imported, which leads to trafficking rings.

It's extremely difficult to stop gangsters from trafficking because they operate in the trafficked persons home country as well, so if you run to the police in Germany or Canada they can seek retribution on your family members back home in Ukraine, Vietnam ect. Thus the not legal nor illegal does a good balance of preventing super brothels opening up full of imported sex workers while at the same time being able to arrest pimps without relying on the testimony of the sex workers.
