Perhaps that homeowners association stays as the developer, and we write laws and regulations that keep the developer beholden to certain standards of maintenance and safe living standards. Perhaps competition will arise between developers who advertise certain levels of amenities and service. The basic minimum can be run by a government housing corporation that sets the baseline standard of living for all other developers to measure themselves against.

The possibilities here are endless. We don't have to keep living the way we do in the USA.
