Call or email your US Senator and ask them to introduce a bill that ties restrictive land-use and zoning regulations from States and municipalities to loss of highway & transportation funding.

It's time for some national policy on housing that makes a difference locally, and we need to use the stick. This idea came from Brian Deese, who was Biden's Director of the White House National Economic Council in this article. https://www.foreignaffairs.com/united-states/why-america-struggles-build . I heard Ezra Klein reference this in a recent interview, and I have to agree with this approach.

This approach is similar to the The National Minimum Drinking Age Act of 1984, in which the Federal government was made to deny some transportation funding to states that wouldn't raise the drinking age to 21. All states complied, and this is the reason why the drinking age is 21 in every state. Monumental change from a bill like that should be replicated for this problem of high housing costs.
