I have to completely disagree with you here in terms of parking. Cities absolutely need to do significant transportation planning or you get the mess that exists throughout huge portions of the developing world. Even Los Angeles with it's traffic problems doesn't even come close to Mumbai. While governments aren't always good about solving these issues, the market would be worse as it's too decentralized to care about tragedy of the commons type problems. Additionally, I also indirectly disagree with the last two points because it is absolutely crucial that cities have some control over population changes as it relates to density. Utility overload is a real issue, and needs to be accounted for. Schools need to get built, sidewalks widened, and so on. What's ultimately needed is a form of adaptive city planning, that reacts to market forces (such as population changes, desire from developers to build new buildings, ect) with planned solutions such that there are no tragedy of the commons issues that come about. What's unacceptable is the 20+ year horizon planning that most cities do now.
