Thanks for the good question. :-) You're right of course, and this isn't going to stop anytime soon. Moreover, even if the world were to evolve towards city-states rather than nation-states, there would still undoubtedly be inter-state treaties governing things like trade / subsidies, copyright / intellectual property, extradition, tax avoidance, etc. These treaties would govern much of what has traditionally been done at a national level, and would render the local force-monopolisers -- whomever they might be -- as simply instruments of a larger system, rather than autonomous actors in their own right. Indeed, one could argue that this is already the world that we're living in. We still draw maps and run political dog-and-pony shows based on national boundaries, but we're already living in a world of post-national urban economies and international treaties, both of which are only gaining strength these days.
