Some firearms require licensing, but not all. (i.e. handguns) And the gun rights lobby screams murder about that. (it's a convenient index/map of where all the guns are, when the nazis want to take them all away.)
A license to drive is supposed to indicate you know how to drive, and it thus a means to revoke that privilege. In reality, it's more a tax than anything else.
Voter registration is there to make sure a person only votes once. If you don't care to vote, then you don't register! If you don't want to shop at Sam's Club, don't buy a membership.
