That it actually freakin' works at doing the thing it's trying to do (providing a currency with a guarantee that each account is controlled by one person)
I don't believe they have ever promised that. One person = one account is not at all how the system is designed. It is definitely never mentioned or promised here: https://whitepaper.worldcoin.org/ and it is contrary to the system outlined in that document.
That whitepaper doesn't explicitly say "one person = one account", but it seems to be a really basic feature of the system:
- They clearly don't want accounts that don't belong to a person ("Keep the Bots Out" is an explicit goal).
- They also don't want one person with more than one account (World ID is intended to solve the problem of governance by ensuring that each person gets only one vote).
Methinks you're committing the etymological fallacy. Crypto is not cryptography. Crypto is a specific subset of cryptography, quite far removed (in purpose, if not in technology) from normal cryptography.
