And since all the stress involved in procuring drugs will be eliminated, the possibility of the self-medicated going nuts and killing people for the joy of it will be a thing of the past.
"A gramme is better than a damn."
Not eliminated but reduced to no more than the level of alcohol crime.
and if you can't afford them, the government will give you your daily fix dose of medicine free of charge.
I'm against that (as is every libertarian I know of).

"Stress" is the opposite of "joy." But I think you're right that lowering legally-imposed stress will reduce violence. As for "self-medicated going nuts and killing people for the joy of it": I know of no case where someone known to have no propensity for violence for the joy of it acquired that propensity under the influence of any drug; it seems that people with a propensity for antisocial behavior are disproportionately likely to use legal and illegal drugs.
