So if he were to die from an illegal substance you provided him (or sanctioned him to obtain under your care) you would see no difference between that death and one that wasn't violating the law? I suspect your angle wouldn't get you off in court.
And when did I claim otherwise? I fully expect that were I caught, I would be punished, regardless whether I believe the law is just or not.
And yes, I believe blue laws such as these are unjust and unworthy of a society of free men. Doesn't mean I think I can break them with impunity.
