Well, I guess no one has any sort of fact or study to refute this.
Didn't the NFA of 1934 effectively raise the price of all affected firearms by $200? Do criminals have a hard time getting full-auto weapons? Or short barreled weapons? I know it makes it more difficult for me, as a law abiding citizen.
I also have a question about your suggestion. Who gets to set the price, Congress? That makes me feel better about a price floor.
