That's a lovely notion, but time and time again, harm minimisation has been the only successful method to deal with issues like this (eg needle exchanges for IV drug users, allowing abortion to prevent women dying awful deaths from botched backyard attempts).

I'm happy for you to start a worldwide movement to end violence and abolish mental illness, but until then, I would rather that nobody has the ability to murder large numbers of people when they feel like it.

And seriously, how many people can successfully weaponise anthrax?
