Ok I have been convinced this is a technically feasible solution that could preserve privacy while reasonably limiting misuse. That said I'm worried that the document you linked does not require relying parties implement the zero knowledge proof approach. It only requires that they implement the attestation bearer token approach which is much weaker and allows the government to unmask an account by simply asking the relying party which attestation token was submitted to verify the account.
