Disregarding the misaligned incentives of for-profit enterprises delivering the kinds of services that are traditionally handled by governments, what evidence is there that technology can materially improve many of these services? Many of the needs listed in the post (housing, education, food security, etc) are largely challenges of resource allocation. I'm skeptical that a web app can somehow make landowners willing to encourage increasing the housing stock in a city.
