You're right, but I think it actually reinforces the OP's point.

How do you make the adamantly noncompliant comply? You can ask nicely, you can threaten, you can stomp your feet, and if that doesn't work...then what?

I hear you but... nothing. We can't force drug users to not own drugs. If you have a gun, keep it, don't comply, rebel! There's no need to force it from you. Forceful removing comes up a lot but gun control isn't about eradication, like polio!

The point about gun control is that it's not owning the gun, it's _using_ the gun. There'd be additional penalties if you shot someone!

Sure you can, and we do all the time, we lock them in cages.
