It is in the figure as a part of the housing policy proposal of a presidential campaign. The executive of the federal government doesn’t control city councils so it must be federal regulations that will be impacted.

That depends heavily on how you are counting regulations in this case. You are increasing the number of enforced federal regulations while the regulations at the local level may be increased, decreased, or unchanged based on how local regulations interact with the federal regulation.

So then the federal government should regulate zoning laws. Which is the opposite of fewer federal regulations.

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.

The conservative court would just rule it wasn’t an official act and say he could be prosecuted for it. They have no qualms with contradicting themselves for whatever political goal they are seeking to achieve.
