There's nothing inherently wrong with using an image of my face to provide certainty of my identity to assure a fair transaction. Hypothetically, it could be the most effective, efficient, cheap, frictionless way to do so. It's what our eyes do naturally. The technology does not necessarily have to save any new data about me , it can conceivably be a device that I own, that creates a comparison with known information about me, signs it, and sends the result of that comparison, not the comparison itself, to the entity awaiting confirmation.. I am opposed to centrally housing data for comparison. However, I can be easily identified by the information that corporations already have saved, and what I have posted on Nostr, personally. For others, the right to choose any other way, or no way, must be defended. There should never be only one set of rules for everyone to transact by. TLDR, not if governments or colluding corporations or militaries or mafias are enforcing it. Maybe, maybe, if it's an open source device that I own. But never mandatory.
