From a tech perspective it has been a solved problem since about a decade ago, via DID (decentralised identities) and their Verifiable Proofs.

The EU digital wallet framework is built around those, and your suggested scenario is a first class citizen.

It is now moving from the academic/research world, to the political field, and feedback/pressure from both commercial groups and political agendas is muddling the field.

Here are some links to canonical docs, you can easily find high quality videos that explain this is shorter/simpler terms to get a grasp of it.

A note: it’s one of the healthy byproducts of the blockchain age, don’t get sidetracked by some hyped videos from crypto bros.

It's a "solved problem" that didn't ever need solving in the first place.

Preserving privacy within a rule based democracy is important to me.

This is the foundational tool for 450 million EU citizens, so I think is very important.

We likely have different interests.

Buying alcohol online without having to show a website or a delivery driver my social security number is a challenge that needs solving. Same with picking up expensive parcels from package drop-off points in my country.

You can debate whether setting up such a system for things like social media is a necessity or desired in the first place, but being able to show someone a QR code that verifies my name and age without exposing all kinds of other details about me is extremely useful.
