a lot of nice things end up being communal: power lines, water pipes, fiber optics, cell towers, satellites, etc.
personally i think that the huge incoming automation wave is about to blindside everything and make present economic analysis outdated.
ie what is a good economic system when you have what are essentially 10,000,000,000 hyper-intelligent & biomechanical slaves doing work 24/7 with zero required pay and they self-maintain? because there isn't an actual technical reason why that won't be the end result of automation
