The problem with that is that sites/apps will retain the identifier, either to use the Digital ID for login (not just one-time age verification), because they want to retain as much information as possible for later usage or sale, or because a government told them they have to retain it so all their social media activity can be easily linked to them.

I have conspiracy theories about the conspiracy theories about digital ID. The people who benefit the most from fake people posting are spambots, sockpuppets, disinfo peddlers, and astroturfers.
And either way, I firmly believe that a site should be free allow you to log in without a digital ID... I just would like to be able to know who doesn't have one so I can know who's a real human being and who is an appendage.
