Tangentially, this is why (despite being an extremist for privacy) I've somewhat soured on Internet anonymity. Very few people are using their anon status to further discourse, i.e. like Publius. Mostly it's just people who want to sever the reputational thread between their output and their person.

I think it's fine to be pseudonymous, like Gwern, because while your government identity is protected, the pseudonym is a persistent store of reputation across time.
