How should a government act to prohibit misrepresentation of one’s characteristics online, from accessing services for which that government has formally defined regulations based on characteristic into law?

If your answer is “they shouldn’t ever do that”, then you’re promoting an uncompromising position that governments are disinclined to adopt, being the primary user of identity issuance and verification on behalf of their citizens.

If your answer is “they should do that differently”, then you have a discussion about (for example) ZKP or biosigs or etc., such as the thread you’re replying to.

Which of these two paths are you here to discuss? I want to be sure I’ve correctly understood you to be arguing for the former in a thread about the latter.
