To use a somewhat similar situation, AFAIK at least some things tend to be defined when you have multiple homes, or live in multiple countries : there tend to be minimum durations for living somewhere that give you rights and/or duties.
Of course it's something harder to implement for true nomads, but some framework is already there. (And there's typically framework for nomads too already, though they historically do tend to be treated as very low class. As a fun fact, the concept of identity papers comes in large part from factory owners which tried to prevent otherwise nomad workers to flee bad working conditions.)
