I agree the original comment was ambiguous. It's widely discussed that the incentives for suburban housing are the laws prohibiting high density, e.g. minimum parking requirements or zoning rules that just expressly ban tall buildings. But in theory you could get there by e.g. prohibiting parking areas, which is silly and pointless because the reason for the existing laws requiring them is that a free market would produce less of them than there are now.
