A hash of a biometric has the exact same negative properties of a biometric data point itself: That it is not concealable, you cannot change it, and that it is tied to you explicitly. Surely you see how a giant database of biometric hashes provides the same usefulness to bad actors as an actual biometric database? It's a unique identifier tied explicitly to your physical body. Anything that hash is tied to can later be trivially de-anonymized. After collecting everyone's biometric "ID", that database can be helpfully leased to Peter Thiel's (one of the early investors) wonderful surveillance machines, so now when the officer pulls you over "for a broken taillight", their body camera can get a nice view of your iris and buy your entire worldcoin history from say Palentir, for a price of course, and zero warrant.
