Worldcoin could only be considered the right thing to do if one's understanding of human identity is constrained to its relatively recent bureaucratic forms, and if the application of such understanding is constrained to bureaucratic contexts. It is wrong otherwise. Harmful in fact.

You note endorsement by state agencies, but to state the incredibly obvious, state agency personnel are bureaucrats.

Computer science formed to serve the bureaucracy; governments and large companies were its first customers. It is little wonder that computer science thinking has much in common with bureaucracy.

Buterin is a well-meaning and talented individual and leader. His grasp of web3 technology is likely peerless, and his analysis in the article you link to only errs in its omissions. We are contemplating sociotechnology and he does not yet exhibit a sophisticated understanding of human identity as a contextual sense-making process, or then how the matters under discussion affect such processes.

Rather than continue my line of argument here, may I point you to Human identity: the number one challenge in computer science.
