ZKP doesn't solve the problem of issuers colluding (or being forced to cooperate) with verifiers

eIDAS in Europe uses ZKP and seems to be working.

I have no idea what you mean by that.

1) It's one thing to use secure auth to access government services, banks etc. that need to know beyond reasonable doubt who you are to function at all. It's something else entirely to require every person in the EU (not just citizens) to ask the government for permission to speak online.

2) What does eIDAS fundamentally have to do with ZKP? There's one reference to ZKP in the 2024 update (https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=OJ:...) which merely says states "should" use it. Doesn't mean much of anything by itself. To my knowledge, the ZKP-based AV shit is only being prepared to run and hasn't been in use yet - https://www.politico.eu/article/online-age-checks-are-coming...
