Eh, "proof of personhood for crypto" is not part of the design by design. The whole idea of crypto was to establish a channel that is harder for one government to control. In that sense, it kinda succeeded. But with that success came attention of various interested parties, whose goals are anything but the original intent including compliance with KYC/AML laws, which crypto mostly ignores ( exchanges don't, but it is a separate story ). In short, "personhood" is not a problem.
