I've tried to follow the NRA logic here, and I think it goes something like this: If an item delights a lot of people, even if it is shown to pose a danger to the public, governments and courts cannot restrict its use. Heroin, therefore, should be legal because a lot of people are addicted to it and willing to buy it. A cool-looking automobile might be proved unsafe, but because a lot of customers love it and are willing to buy it, the government has no business restricting its sale and ownership.
