I’m not sure how much government has ever done to encourage innovation and investment at the local level. If one is a true believer in last-mile natural monopolies, then it is clear that the last mile should either be a) run by local governments, or b) run by regulated monopolies, for the benefit of consumers. I’m not sure how wide that gulf really is: Government run vs. private, but regulated. How do you provide incentives to build infrastructure that can only end up as one or the other?
