gun registration and owner licenses
Well first of all the license scheme for automobiles were designed for tax collection reasons. LATER it began to be used for criminal investigations.
Second, the ONLY reason it is useful in criminal investigations is because you are required to have a tag out where everyone can read the number. Try solving a crime where an auto was used without a tag number.
A tag would be a bit awkward for a firearm one is carrying. I guess we could wear our "tag" around our neck.
Third: It is the law of the land that "we the people" put into our Constitution. Not so with automobiles. (Maybe it should be though)
Anyway, that is my short response.

The reason one has to have a driver's license to drive is because they will drive on public roads. One does NOT need a driver's license to drive on private property.
