[Skidoo]

There is just such a widespread illicit market in automobiles: Mercedes, to be exact. But, again, the comparison is inexact.

A stolen organ is not a knockoff etc. of a legitimate item. Once the illegitimately obtained organ is introduced into the supply chain, it is indistinguishable.

It would be like two types of wheat differentiable only on the basis of their sources. That's a distinction without a difference. Dealing in unlawfully obtained organs could become a more profitable business model than that of lawful organs, depending on the means used for acquiring each and the easy with which the bad guys can slip their organs into the legitimate marketplace.
