Legalize and regulate prostitution. But, no child traffickers! Those things, and those running kiddie porn and child trafficking rings have forfeited all their rights to be here on earth and all other civil rights. Adult traffickers deserve life in prison, or the death penalty (depending on the circumstances involved in their trades)--and those who use deceptive practices deserve to be shut down. Hence, no setting up brothels under the guise of working for a supermarket or other place of employment, or forcing employees in such to do prostitution or lose their jobs.
And yes, it needs regulation. Out of control prostitution leads to bedlam. You get them in neighborhoods where they are going to ruin the areas. You also get drugs, which do not mix with brothels. And no giant holding company should be allowed to run these businesses--any conglomerate prostitution "business" needs to be stopped before they can create kiddie porn rings, forced prostitution, or trafficking issues as companies that are too big to be stopped. This means that Walmart cannot enter the prostitution business--they need to be kept independent but under regulation to keep them from becoming drug businesses or trafficking circles. And I am in favor of a minimum age of 18 to work as a prostitute, just as it is for regular porn.
