Having reliable personal identities would enable some interesting stuff, like inflation-funded basic income, reputations, and loans without collateral. But I don't really think having a central actor collect biometrics is a good or safe way to achieve it.
Here's my US passport, a drivers license, a picture of my home, some tax records, and you can verify all of this beyond a reasonable doubt via the various credit reporting agencies. Now hand my my $100k please. Oh BTW I don't actually have any money in the bank and I have no income and etc so you're never going to see me again and good luck collecting anything.

In a way that, like, say passports, have never done?
