People are going to take drugs anyway. Let them.
Just don’t cut them any slack if they commit any crimes while high.
Not a problem with most pot users! Their crime is "getting caught".
That’s a bit like saying “teens are going to have sex anyway”, right . . . ?
The class libertarian argument. Laws don’t work. People are going to do stuff anyway. So let’s get rid of the laws and get high.
But laws, while imperfect, do work. People might still do bad stuff, but they do much less of it. They fear the physical penalties (jail). Or more importantly, they fear the moral sanctions — the disapproval of law-abiding friends, parents, media and church.
And cut them off from public health care.
