Yes, and “travelers” have historically had their own systems of law and governance.

The US military being an excellent example. Extraterritoriality for merchants was a big thing in the 19th century. Ecclesiastical laws was a big thing before that (not all clerics were travelers - monks needed their own legal system for the opposite reason).

But nobody said “screw physical jurisdictions” - they just created a new, non-territorial jurisdiction for a select few.
