Nobody thinks that we can prevent everyone from doing something. The point of regulating (or making it illegal) and then enforcing those laws is to increase friction, increase costs, and thus making the thing difficult enough to obtain that the problems it causes become manageable. If there are 3 vendors of this sort of thing, then shutting down one of them definitely will make it more difficult for would-be customers by increasing costs and risks. Something does not have to be perfect to be good.

> They're kind of like arms manufacturers. Do you blame them if your government shoots you?

When Iran sells weapons to the Russians we definitely blame them, yes. And the Russians for using them, as well.
