Sure, the polity that is most important to one will change it's name and it drastically depends on the person. The current nation state is not the most important polity for a lot of people because technology is competing with it.
But I'm not saying that I want that to happen or not. I personally certainly don't need or live as if I needed the nation state. I'm a voluntaryist at heart, I live as if there were no states. In essence I personally don't care about any of these nation states.
But that doesn't mean it's not important for millions of people, that there's no real politik for millions of people that know zero about this. For most people the nation state is and will be the most important polity in existence. We can't ignore this fact and that's mostly what I'm referring to.
And in that sense, the US is revolutionizing the nation state arena.
