Uh, no thanks!

I'd like to avoid solutions that facilliate an implicit assent to the collection of biometric data.

The plan you've outlined still has large organizations building massive libraries of immutable identity data. (they'll still have the fingerprints, however mixed and matched and re-ordered, and they'll still have the scanned faces)

At the end of the day, we'd still be letting them, asking them, begging them to store our finger prints and recognize our faces. Putting bald data in the hands of amoral, faceless, collective entities like corporations and governments.
