I've had some thoughts lately that these issues are closely linked with physical borders.
In the old days, people with similar ideals would gather in physical proximity. Eventually, their common values would form nations.
In today's world, it is trivial to find people who share similar values - but they might be on the opposite side of the world.
We are doing nation building in a virtual space, but we are unable to realize them because we reside within physical borders that we did not draw, cannot change, with mismatched governance.
The values of everyone around us have changed - and we are stuck in some type of twisted hell of a prison where we can't escape those we don't share values with. Your neighbours are now on the Internet. Some of those people might be your physical neighbour, but many aren't.
