I also have my familiarity from those same sources and I do agree that it imitates his neocameralism ideas. The mistake in my argument is that I considered the single-user system where the user controls root, so you're very right. Since urbit is a distributed system, its design will have political implications. Ironically though it would give you more control than current systems, so that's kind of an argument in his favor. As far as I could tell, I didn't see any aspects of racialism or slavery in urbit.
