Earlier quoted context omitted.
I still don't understand how someone is supposed to benefit from such a thing. If I want to use some service, I'll sign up for an account with it. The only thing a centralized ID is going to do is let the service correlate me with a different account on a different service, which is exactly the thing that I don't want. How is someone supposed to benefit from a thing whose only function is to reduce the friction again…
A well implemented system would somehow allow you to use your ID to prove you have the attributes a service needs (being over 18, able to drive, no criminal records, not a communist or whatever it is they need) without providing any further information that would allow multiple services to correlate ID's against eachother.
And doesn't address many of the other problems (eg accuracy)
