I think the key contribution is uncovering the implicit assumptions behind the concept of a singleton agent. Is a nation-state a singleton? If not, why not?
I agree. I think it is pretty hard to cleanly divide something into a single agent or multiple agents in general. Practically, this means that it can be useful to model something using different frames (e.g. a single agent or as a collection of agents).
