I would add that while zoning reform is something that all Georgists should get behind, land rent as public revenue is really a separate issue. It is worth doing even with the present zoning in place. Consider a scenario where society is at a technological level where the only type of development possible is a single-family home. Rent as public revenue is still the most efficient and ethical tax base for society. Land assessment is based upon the highest and best legally-permitted use. If it is -only- possible to build single-family homes, this does not diminish the case for land rent as the tax base.
