The stupidest thing is you can go to another state and buy a gun in Walmart, why even bother to build a plastic gun in the US?
Asking why someone would want to do this is just not trying very hard in the conversation is actually pretty myopic.
Of course, 3D printed plastic ammo isn't likely to be very effective.
(Maybe they're worried that before long, 3D printing with metal will almost as easy and affordable as plastic 3D printing is now, and people will be printing off entire arsenals of very effective firearms?)
It is illegal for the government to make a registry of gun owners. There is an electronic check to clear you as a legal gun owner but there is no registry.
