Scott Alexander presents counterarguments to YIMBY housing policies, questioning their effectiveness and considering NIMBY perspectives. Longer summary

Scott Alexander steelmans the NIMBY (Not In My Back Yard) position against YIMBYism (Yes In My Back Yard) in housing policy debates, particularly focused on San Francisco. He argues that: 1) San Francisco's housing growth rate is not uniquely low, 2) Building more housing may not significantly lower rents, 3) Increased housing supply could potentially increase rents due to agglomeration effects, 4) NIMBYs have valid reasons to oppose development, and 5) Increasing housing supply might trap more people in an undesirable equilibrium. He concludes by acknowledging the lack of clear alternatives but expressing skepticism that simply building more housing will solve the problem. Shorter summary
