I guess what the government is afraid of is counterfeited CCW cards. What we need first is a National CCW card, which I don't want, since I like the idea of Chicago, New York and Washington D.C. serving as our bad examples. If we had a National CCW card, then we can have grades on where you can carry.
This, of course, is opposite of what the Second Amendment means.
We do have a national CCW card - it is the Second Amendment to the U.S. Constitution.
