There seems to be a general sense that short-term rentals make housing unaffordable. I disagree. We came up with the technology to scale a given piece of land to hundreds of residents at a low marginal cost a long time ago. Unfortunately, we've outlawed that technology in the vast majority of the American urbanized area. As a result, the demand to live on a particular piece of land far outstrips the supply of homes, and this competition makes prices skyrocket. Build more homes. Build a lot of them. It's the only way to keep our cities affordable.
