Jon Stewart's plea for gun control

I enjoyed the emphasis Stewart made about the part of the second amendment people love to leave out: "a WELL REGULATED militia".

But as for a suggestion, can't we just reduce the number of guns available to everyone, and make the just a little, not a lot, but a little harder to own? Not buy, but own. I don't know the first thing about gun registration, but can we treat it like car registration and car licensure? You have to renew the gun every year, your license every 4 (with a "looney" test). It's annoying, but the "don't take my guns" people get to keep their guns and the "more gun control" people get more control of the guns.
