You're confused. Cheese can be regulated not because it's practical to block it from being distributed. It isn't, and if you prohibited it you will create a black market. Only after you've created the black market through prohibition, does regulation then become impossible. Every single bad thing you can think of about drugs isn't caused by the drugs at all, but by the prohibition. And the few exceptions to this that someone might find... those rare bad things not caused by prohibition itself aren't actually reduced by prohibition. They still happen anyway. The junkie who is ruining his relationship with family still does so today.
