Re-reading, I definitely mis-spoke: I meant I've spoken about a government provided email system, as IDs are standard almost everywhere except perhaps the UK. Yes, I do agree that the problems with a central ID are solvable instead of the insanity of the US system.
Are you saying this doesn't exist? Idk about other countries, but at least in Denmark they have this today. While some people quibble about various small issues with the system, I definitely think they're much better off than the US.
