You want the Gov't telling you how things have to be done? It's just going to lead to even more restrictions and possibly taxes.
It's already illegal for a Felon to posses a firearm. You should just ask to see a LTCH and call it good. If they don't have a license to Carry they either should get one or can't own a gun.
but not everyone would do this they DGAF. Isnt that the point of a govt. tell you you cant do certain things so people dont get away with murder(figure of speech) is it any different here? freedom of speech, but you cant yell FIRE in a crowd to cause panic
