The only thing proposed that's reasonable is "changing regulation." It's too easy to block new housing, and often times it's just flat out illegal to increase density or build mixed use.
But those regulations are largely controlled by local governments, not the federal government. Federal regulations can prevent building new housing in certain areas and conditions (like destroying habitat of an endangered species), but that is much rarer than a city council not approving projects or zoning changes because they want to keep property values high.
