We're certainly moving toward something more of an International Fascism in contrast with the earlier, nationalist incarnations (very cyberpunk dystopia), and I think anarcho-tyranny is a tool toward that end, but I'm not sure it's a desired end state, nor does its definition allow it to be called a form of government on its own.
I would say the US is slowly shedding the Fascism elements in favor of an Anarcho-Tyranny.
