the US systematically taxes and forbids new housing in many ways as local voters desire. Setback requirements, 100K+ hookup costs, stairway standards, density limits, parking minimums and regulations, community input, allowing rejection of new housing despite it following all rules, abuse of environmental regulations (which ends up hurting the environment by blocking density), affordable housing requirements (a tax on each new housing block to fund affordable units on the side) all prevent new housing form being built.
