The goverment used the existing ITAR laws to block the 'export' of the model to anyone not a US citizen. This is quite onerous to enforce, since it applies to non-citizens physically in the US. So Anthropic shutdown access completely, as the only reasonable solution.

The key point is the government used ITAR. What's being asked for by Dario (and many others) is some entirely new legal process with more involvement and balances that blocks the model for everyone explicitly. But apparently just enforcing ITAR is good enough to do effectively the same thing.
