I am not arguing laws need to be binary-effective. You are right, most of the current laws are designed to slowly erode public support for the 2nd amendment by making the barrier to entry so absurdly high that the average person cannot feasibly own firearms.

I am arguing that the new laws being proposed (e.g serializing other firearms components, ammo serialization, assault weapons bans, higher gun-owner standards) have absolutely no bearing on an entirely new source of firearms. Many Dem-controlled states have passed "ghost gun" regulation, but there is no real enforcement mechanism and it's mostly an additional charge to tack on after an actual crime has been committed.

You can see states like CA trying to go after 3D printers, but I suspect this will fail. There is no software out there that can realistically determine whether a part is a firearm component, other than dumb hashes of known parts. 3DP is a general tool, it is like trying to ban milling machines, files, or basic handtools.
