In supply constrained areas, more SFHs are physically impossible. And the more people who are allowed to live in their preferred multi family units, the more SFHs available to those who prefer them. We don't block SFHs anywhere, there's no minimum density. However we block higher densities nearly everywhere. So blaming the people wanting higher density makes zero sense.
