> I'd probably sleep safer if I knew that there's no easy way to anonymously obtain necessary ingredients That is already the case for a lot of things, when it comes to chemistry anyway. Your random person couldn't get their hands on the things required to make various dangerous chemicals. Criminals, they can, sometimes, but with great effort and expense so it's usually aimed at chemicals that will make them money (drugs, typically) -- and the really advanced stuff is done by "legit" (kind of) labs, not a home chemist. Of course, that's only as good as the stores following the protocols, and with the internet that can change somewhat, but even then it requires buying chemicals outside of the country and getting it through customs (which isn't perfect, but puts up enough of a barrier that regular people or average criminals don't risk it).
