I too think it should be a personal choice. Not saying it isn't a good idea, but I don't like decisions taken out of my hands and made by the government. If people want to use bad judgment, it just helps clean-up the gene pool.
In 1979, the 18-year-old son of a good friend of mine was driving when his car hit a patch of ice, and he wrecked. Not wearing his seatbelt, he was thrown out of the car against a tree, and has been a quadraplegic since; the car had very little damage, and if he had remained inside it, he would have, too. He's still alive (if you call that living), but he wishes he weren't. He managed to go to Yale for 3 years, with much (very expensive) help, and then dropped out. He hasn't done anything since, and he and his entire family have sufferred from his injuries every day. If personal choices only affected the person making them, I might agree with you, but they don't - admit it or not, we really are all connected.
