Why is that an issue, it solved the problem. And kept losing means he gets it back: just do not give it back. Then we have one less drunken driver on the streets.

But from the perspective of wanting drunk drivers off the road, it worked, yes?

IDK if that's true. Consider that a real alcoholic drinks all day long and truly can not control this. Typically they tolerate alcohol better than the rest of us, but still, there also comes a time when they are simply bombed and then they are (really) a huge danger.

A casual partier though or even someone heading out and thinking they will take the chance of driving home and getting there ok, then yes I agree.
