"You see it in marijuana legalization, where some state’s are so restrictive about licensing sakes outlets that legal weed costs more than illegal. How can that kill off a dangerous black market?" Look at consumer products: generics or store brands are available for all kinds of products yet the substantial majority of sales are for branded products. And here the generics/stores brands are fairly similar to the branded products. But in the illegal drug market you have little idea of the quality of that product--so consumers will pay substantially more for products where they know exactly what they are getting [in this case the legal products].
