It is interesting, the idea of a oneness of the human population on earth vs national soveignty. There are those that consider how or what, if any, change in the "virtual reality of social norms" would either be or have to be affected/effected.
IF one were to examine various scenarios, and give opinions and ideas toward one or the other, they may seem to favor one or the other or some particular approach.
There is, also, the reality beneath the "virtual reality" and ideal human behavior. Especially in light of history vs propaganda and the tearing down and indoctrination of people, empires and states over the course of mankind.
I have considered these over the course of my life, though not as a major focus on solutions, at this point, but rather as to how it affects/effects human nature and interactions.
