Encryption is a better example. The USG tried exactly the same tactic in the 90’s. The NSA tried to shove the Clipper chip down everyone’s throats. The USG put export controls on encryption and people went as far as to tattoo the algorithms on their body.
But like you said, they will try to control it and fail. Like they always do.
I can't wait for the first person to tattoo model weights on their body!
