There is the need of a citadel/utopia where every digital nomad could ask and get a decentralized-residency even not being fiscally there. You obtain it thanks to confirmation of certain specifics and values (ex Bitcoin address, a nostr account verified by a number of people confirming you are not an AI or bot.. etc.) and that gives access to passport, driving licences.. something like that happened in small attempts already in different places, where some visionary created His small miny-states.. no I am not talking about the episode of Family guy 😅, one of them was made on an dismissed oil extraction sea platform just outside UK cost in the 1967 by the Roy Bates family. See the link below, an amazing story, good for a book or a movie.
