You’re missing the point. They’re taking into account that some people will try to get around it. You’ll be dealt with eventually if you think you can keep ahead of their laws.
The goal is total control, and if it means banning big sizes, then banning small sizes, then taxing it like cigarettes, then banning it altogether, then making smuggling it across state lines a crime, then making mere possession a crime, then making it a crime not to turn somebody in who has some, or might have some, then that’s what they’ll do.
This kind of thing has to be fought head-on, not tiptoed around while we quietly giggle and marvel at our own cleverness.
Hell, I speed and drive in the carpool lane.
Bring it, lawman....
But in truth, this will ALL FAIL.
