I usually dislike the idea of inviting government into this space, but if there's anything that governments have traditionally done decently well and should do (it's usually within their mission statement) its identity. Passports are really the primary identity layer of Earth.
Ideally in a perfect world we'd have governments run OIDC systems similar to the US login.gov and these would delegate from an international master OIDC system at the UN. Everyone would have their citizenship passport ID and their UN ID, and the latter could serve as a "break glass" master key to support immigration and also limit the ability of countries to "digital death penalty" people.
I can think of some dystopian outcomes here, but IMHO they are not worse than the dystopian outcomes that come from corporate monopolist control of digital identity. At least in democracies one has some nominal influence over one's government and the latter is bound by the rule of law, and if you don't live in a democracy you can (or should be able to) leave.
You're right that identity is hard, and I think most of why it's hard is human rather than technical. One could create a decentralized identity layer from a block chain fairly easily but people would lose their keys etc.
