We don't control access to alcohol, paints/volatiles, aerosols, and so many other things people abuse.

Just yesterday on Reddit there was a thread that went viral for "cutter" reviews on Shein razor blades, with cutesy language like "beautiful beans for my followers" (referring to subcutaneous dermal appearance when deeply cut open). Every product can be abused in horrible ways. It's the nature of the stochastic bubble we're in. People will find every nook and cranny of the human experience.

You can't stop this stuff from happening. So at least let the normal use cases that benefit society through. Don't put everyone else in the same straight jacket. We don't deserve to be punished for the bad gradients some people fall into.

Ok, if you want to control it, than mediate access through a public health institution.
