California is trying to ban the sale of 3d printers that don't detect and block "gun parts" from being printed[1]. All Anthropic and friends need is some kind of safety rationale and we won't be able to buy computers that can run local models.

The plausible way to do this is to force all software through some kind of signing process. This would be trivial for Apple to pull off and not much harder for Microsoft. On the Linux side, I expect the systemd folks would be happy to add some kind of signature checking to "head off the inevitable".
