In the short term, governments can suppress free distribution of open weight LLMs. For instance, they could "ask" Hugginface to require an account with a university affiliated email address to download anything. It won't stop you outright, but it will force it underground, slowing everything to a crawl.
In the long run... well, general purpose computing is under threat anyway. Platforms with locked bootloaders and mandatory digital signatures outnumber those that don't. Even on "PCs", the openness is merely a cultural norm observed for a particular market segment[0] by Apple and Microsoft - for they are the only ones with true root keys. Even a brand new motherboard comes with Microsoft signing keys pre-flashed, and you are permitted to enroll your own only by grace. The technical infrastructure to flip a switch and lock it all down is now in place, ready to go at the stroke of a pen. Will you be able to get Llama.cpp from "the app store"? I hazard not. If you think this sounds hyperbolic, look at what is happening to Android.
[0] They don't even segment it the same! Apple segments by "does it have a keyboard", and Microsoft segments it by "does it have a native x86 processor". Apple runs different software on the same basic hardware, Microsoft runs the same basic software on different hardware, but both have created artificially restricted second class computing categories.
Well I guess all your points are true for Europe but I don’t see how for America. (because freedom) it will certainly cost more but also it already does.
Not "banned" per se, but functionally impossible to run on hardware that's powerful enough to be useful. It's not a stretch to imagine GPU drivers that refuse to run unless installed on a fully "attested" system. We're already there with video games, it's called "anti-cheat". They'll call it something like "AI abuse protection".
