The "criticized the president" scenario is already simply a violation of the first amendment and not done, and the gun thing is plausible with or without CBDC.

I'm not stumping for CBDC, but these examples seem to carry the assumption that the government would be doing them were it not for practical barriers that CBDC permits them to bypass. But I think the government could do them now, it just doesn't.

I'm not actually sure what the social media thing has to do with CBDC at all actually.
