Rachel's Ecstasy would have still been illegal if the moonshine model is followed.
Nope. If Ecstasy were made legal but highly taxed, then you could say "Rachel's untaxed Methylenedioxymethamphetamine" was illegal"...but in that case, there's little likelihood she'd have been dealing in untaxed MDMA, with brand name Ecstasy available. (Of course, the UN prevents Ecstasy from being "brand name" but that's another story.)
Or do you fail to recognize that there's little reason to buy an illegal form of alcohol when alcohol has been made legal but is highly taxed?
