Ah. Again, you are a victim of your ignorance of US jurisprudence
The Second Amendment protects an individual right to possess a firearm unconnected with service in a militia,
As such, "Well regulated" modifies "militia" and thus has no effect on "the right of the people to keep and bear arms"
Thus, I accept you concession re: "Arbuitrary and capricious"
You can ignore the jurisprudence , and the explanation contained therein, if you want, but it just means you don't really want an answer to your questiom.
Irrelevant to the point.
You want to equate driver's licenses to licenses for guns, but to do so, you must allow convicted felons to own guns, w/o restriction.
