The article discusses how nice, walkable places are often associated with being expensive and exclusive, but argues that this is due to scarcity rather than the design itself. The author suggests that if more of these places were built, they would become more affordable. The article also touches on the idea that zoning regulations and other policies can hinder the creation of walkable neighborhoods. By increasing the supply of walkable places, the author believes that the prices will decrease, making them more accessible to everyone.
