Eh. I wouldn't doubt that some spark will rally for it to happen - not at the national, but at the international, G7 level. And then they'll press for some electronic disabling device 'only available to law enforcement & the military.'

Pretty much a dumb idea, though.

First, law enforcement might come to rely on that whilst ignoring a great deal of firearms already in the population that don't have the chips.

Second, you'll be creating a black market for chipless firearms, whether new or used or smuggled. Consumption is never a constant - which people tend to forget - so purchasing wil 'route around' the interference.

Third, making a firearm from kits or from scratch [machined, that is] isn't such a big deal if you're at all clever. More folks would find that attractive & get into that hobby in result. And there would then be more dangerously unreliable firearms in the population. Some of them fully automatic.

Doubtless some of the newer firearms owners would start off with the chipped arms, since they wouldn't know any better. Doubtless also the folks at the local range would set 'em straight very quick.
