Yeah - this is a problem. Well, let's see, how do you feel about the "big" federal government, in this context:

I mean, the argument would be: the world is changing. There are "many" more people than there used to be, and therefore "much" more opportunity to do something wrong. Furthermore, we live in a dangerous world, where an individual can cause massive destruction just by going to the store and buying a few over-the-counter items. So, the government needs to be "vigilant", and make sure that it understands what's happening on the strreet.

And, it would be kinda stupid to have each State replicate all that machinery fifty times, so it makes sense to have the Federal government fulfill that function.

How does that "logic" play with you?
