You kinda skipped the bit I wrote alongside this about strong authentication. There are numerous ways to do this. For example, in Finland you have to physically identify yourself to open a bank account and you can then use that to authenticate. It's used for all public sector services and a few others with strict accreditation.

The issue is that it solves nothing if you can't distinguish between text that is written by AI and isn't, regardless of strong authentication.
