Unfortunately for you, the Right to Keep and Bear Arms is an enumerated Constitutional right, and there are strict limits on the restrictions that can be placed on those.

Any analogy with merely owning a car fails hard, in all but really revenue hungry jurisdictions car ownership has no restrictions of this kind. It's only when you want to put it on the road that you have to get plates and a licensed driver. And there's a vast distance between the skill and experience needed to safely drive a car and use a gun; in just accidental deaths, this shows in the ratio of 58:1 from memory when I last calculated (> 30,000 vs. a bit over 600 annually; I can look that up if you want).
