While official identities may solve some problems, I'm more concerned about the myriad new problems they create, e.g. privacy concerns, who/what is in charge of setup/maintenance/verification/updates, tech literacy of the public, misuse of the data, etc. I also worry about how difficult it would be to the statutes and regulations for such a system. Many of the people creating, regulating, and adjudicating on such a system are not very tech literate. Even well-minded politicians would have a very difficult time creating a benevolent/benign official identity system that couldn't be misused like many of the allegations against China's social credit system. Personally, I would prefer most of my internet use to be distinct from my official identity. But, I wouldn't stand in the way of others that want to have a way to prove their identity. Optional enrollment might be a compromise? If fraud could be consistently prevented and enrollment didn't become compulsory in a round-about way through most large internet adjacent corporations requiring its use.
