An Objectivist America is unlikely. The idea of forming a new state or "state within a state" are quite ingrained into the Objectivist mythos. Objectivists, more so than other forms of libertarians aren't interested in reforming the system or starting a revolution.
It should also be pointed out that a libertarian state won't necessarily be an Objectivist one. Objectivism is a unique ideology with some very specific sets of beliefs and policies.
