Anywhere in North America is habitable, what you are looking for are low population areas. Western North Dakota on down through western Kansas is the least populated place in the lower 48 and there are some places in Alaska that have never seen a footprint. Learn how to work with and keep a dogsled team and go outside of a place like Lime Village, Alaska and you will know what it is like to be in the wilderness. If however you still want to be on a road system, then places like Meeteetse, Wyoming, Edgemont, South Dakota, or even Valdez, Alaska might suit you. I personally like to live in places that are off the beaten trail and not at all urban. I currently live in a place that is a little more than off the beaten track, but I am writing this from my pc in a remote location in Alaska. It's possible to have the best of both worlds.
