More thoughts: Another "friction of civilization" story is the Firefly/Serenity TV/Movie series. It's space opera science fiction with HEAVY HEAVY HEAVY western overtones and themes. It's about living and operating at the edge of things, it's about the gray areas that occur there NOT Black and White good and bad guys. Civilization is a smothering oppressive and ruthlessly enforced nanny state. Interestingly applicable to many issues today.

It is important to remember that the civilization in most Westerns stories is Victorian ... socially repressive, morally strict, and limiting of thought and entrepreneurship. It's rarely mentioned but this is what the "Wild West" was rubbing up against and what people who came west were trying to escape from.
