I gave an example in the previous post how the identity of the user could be hidden from the service.

In both your examples the government service has your full identity, then pinky promises to forget it.

Unless I'm misunderstanding something?

It would be a lot easier to get that information from the ISP.

Not quite the same, as IP addresses are shared through NAT, VPNs exist, etc. With the proposed legislation it is illegal for website operators to deliver content to known VPN ips, as they cannot confirm that the end user isn't a EU subject.

It can be like buying alcohol in a store. They look at you and see your age. Or if it's unclear, the store clerk asks your idea and promptly forgets all about it. Except you're not buying alcohol but a login for some age verifier.

So yes, they get your identity, then promise to forget it.

That's a worst of both worlds proposal: it makes it trivial to deanonymise people, and it doesn't solve the replay attacks.

Maybe buying alcohol works differently where you live.

They ask for ID card indeed, making it super easy to just make a copy. On top of that, your payment details are stored. You're on camera. Etc.

Super easy to automate deanonymization. (1).
