describing a person the way a nation is described
There's lots of ways that nations are described - many of which are just derogatory stereotypes of the people that make them up...

I'm guessing you mean more along the lines of sovereignty?
In our lives, besides gods and ideals, a nation is the highest authority that we can submit to. From birth, we implicitly submit to the will of the nation, and never have a say about it. The nation has the monopoly on force, it alone as the right to wield violent power. The nation is a system through which the forces of coercion can flow. Inside the nation, every single law that we follow is always backed by the coercive force of the threat of violence.
Externally, between nations, there are treaties and laws, but there is no monopoly on violence. If one nation defies the rules (which as always, are backed by violence), then they have their own violent forces to resist the punishment. There is no greater power that the nation must submit to. They are free to express their own will.
Every man is sovereign. He has the power to enforce his will upon his own body, and he also has the power to defy the will of others. However, the nation exists to mediate our individual wills, wielding greater force than any individual in order to do so. The fact that we are coerced into following the will of the nation does not change the fact that every man is sovereign - we play a game where we give up our sovereignty to a nation, but it's just a shared hallucination. At the end of the day, the only rule that actually exists is that we follow our will (or God's will, if you like).
