De-commodify housing.
An active market for mostly-interchangeable housing units is a great thing. No one wants to see a world where housing isn’t a commodity, unless they already live in their ideal home. We want to see a world where it’s cheaper.
Look at Japan- their housing is surprisingly affordable in Tokyo despite being in a major city. Due to flexible zoning laws, houses can be built almost anywhere. Houses are deprecating assets, like cars, rather than investments, like houses in America/Canada/etc.
