Yours is a well thought solution to a growing nuisance. The only rub is the actual passing of your proposed laws. Even in States with Republican legislatures, spineless representatives will cower at the thought of media condemnation for such a practical law or statute.
That’s something Republicans need to deal with in their primaries, then.
On the other hand, such a bill could be pointed out as “we need to protect our shopping public properly, and what we have now isn’t working” as well as “this will provide many jobs.” And hey, this just sets minimum standards of safety, etc., etc.
