Or may be we could go back to the simplest form. Physical Media. I think there is something to be learn from the Japanese on how they value something physical.
Everyone would have their own DNS domain (this was in a science fiction reality where DNSSec was very secure).
That DNS domain would be exposed by their firewall, it would serve a single static domain.
Something like MX records would be setup for simple auth services and one-time payment transactions.
So when I needed to login to a site instead of talking to facebook, the site would talk to the root servers which would hook them up with my domain on my router.
The for a credit card transaction I could authz a transaction between the remote website, my router with my information and the credit card payment provider, so that the website never saw any details.
This would be wrapped with a service so that the home user never hand managed their DNS zone similarly to the way NAS appliances often run linux and NFS without people needing to poke into it.
But it needs to not be written by a FAANG company and needs to piggyback on open standards. Maybe DNS isn't the exact right tool, but it needs to look something very much like that with a hierarchy of open registrars.
OpenID is kind of close to the start of that, but I don't like the way it piggybacks on e-mail addresses and I think it needs to be its own thing and simpler to manage.

What's different about the Japanese in this regard?
