It's in the same vein of using blockchain to track real world objects or use CAPTCHA to fight bots. It all fail on the human-machine interface because the definitions on what is real, where something starts and ends falls apart on edge cases and computers are all about edge cases. Consider a fail-proof CAPTCHA, me personally or through hired humans solving it doesn't prove that the rest of the operations are not conducted by a bot. Consider genuine item tracking with blockchain, it still depends on me digitising the real life item and the blockchain can guarantee only whan happens after that. So this is a weak attempt to solve the human-machine interface problem. Put all the other creepy stuff aside, scanning a retina would not prove that I'm an individual who is entitled to the 25 tokens. The first thing people would do is to exploit as many people as possible to take their tokens. The whole exercise of machine scanning a real life object to verify authenticity is useless.
