Not to be argumentative but I just think that painting the entire world in such broad strokes makes Earth one of the least interesting planets in the entire game.

Not at all - I understand the idea of introducing variety. Earth is a little boring, but I think that's because GDW's writers sort of wanted it that way. They wanted an Earth that was comfortably familiar to most (western) readers: Europeans are still solidly in charge on the surface, the familiar countries are all there, with a little jiggling around to make it seem like the future. It's not how I would have made Earth in 2300, but there you have it.
I just find a continuing romanticism of the gun-toting old west that never existed historically to be a little silly. I guess that's what I am trying to avoid - I find the idea of the gun-toting anti-Federal government American to be pretty much dead on to how most Americans (especially in the west) feel some romantic attachment to some degree or another today. For me, thrusting the game 300 years in the future to make America different would involve compromising that view. Like the Holnists from Brin's "The Postman" I'd imagine in 2300 Earth, the wearing of 1980s style woodland BDUs is probably seen with distaste in most parts of the country, while in some parts it's basically the same as wearing a Klansman's white robes and pointed hood. A combined distaste of soldiers-turned-marauders, CivGov and MilGov ineptitude, and the extensive wearing of the material by New American militias have probably firmly have turned woodland BDU patterns into a politically charged message (the American military of 2300 certainly wears camo, just not that color/pattern).
Plus, I find America's long struggle against New America to be fascinating enough - the fight against New America and likely scars it's left on the American psyche, and I'm certainly not sure NA would have been much of a nanny state if you weren't a white American (I use the term "white" deliberately in this case - as "looking" European is all that is necessary to people like that) - in addition, I don't really equate nanny state as an oppressive state. It can be, especially if someone is constantly telling you what you've "lost", but in most cases people don't really use the freedom they have anyway.
The way I see is that America is still a lot more "free" than other states, but that's because the country is still patching itself together, taking far longer than others due to meddling from other countries and residual New American influence - no organization that lasts that long is going to go quietly. There's going to be people who still very much vote along New American lines and whisper that things were better "back then." Just like a lot of Confederate supporters left the US after the Civil War, I'm sure a lot of NA diehards left the US after the last enclave went away - where did they go? There's another question - was the absorption of the last NA enclaves done via conquest or via voting or treaty? Do NA sympathizers still riddle the American south? Have they moved somewhere else, say Ellis (my personal vote is that they live on America's holdings on AC where they have a sort of unspoken agreement with the government that the government won't harass them if they don't start practicing their vile New American proclivities).
Finally, I do see America's psyche is probably torn between those you describe - the individualists and so on and those in favor of a stronger central state. I suspect even the most rugged individualist actually understands a stronger Federal government is needed at least on Earth, but still doesn't like the idea, so resists it. For instance, there's a note in Earth/Cybertech that indie ranchers and such are being crowded out by corporations, and while the indies know they're going to lose, they're fighting the good fight to the bitter end. I'm sure that kind of thing causes Americans no end of anguish in 2300. Obviously there's some who see it as inevitable and that the ranchers are just throwbacks who really need to "wake up and smell the coffee" while others identify with them.
