I really wished the idea of the gates would be taken more seriously in the books. I wished it would be more clear that for mutants Krakoa is a nation without borders. A nation that is not confined by geography but is creating a "global pan-mutantdom society" that lies in every nation worldwide.
I think one of the truly revolutionary aspect of Krakoa would be to articulate clearly that national borders does not exist anymore. You can live in New York City, Berlin, Dakar or Caracas and still be part of Krakoa's nation.
Jean Grey articulated this idea in X-Men: Red but the editorial X-Men team unfortunately seem to have forgotten all about it.
