Well I thought I explained it effectively, but there are numerous scenarios where you'd want to use the same identity across multiple services, cross sharing of data, provable rights, etc. But that doesn't mean you're limited to one, or that you want to use it for every service you use. The benefit doesn't disappear, the benefit only applies when you want it. It isn't all or nothing.
You just described OAuth/OIDC.
OAuth helps but it still forces you to rely on a single central provider as your "root". So it's not a complete solution.

So what ? I am still struggling to understand what immediate and painful need users have with trusting Apple, Facebook, Google etc with their identity.
If people had some issue with this then users would simply not use OAuth and default to creating an account for each service they use.
