New towns are less efficient than densifying existing cities. With new town, have to build all the infrastructure. New roads, new schools, new utilities. The transport is less efficient by driving everywhere. Single-family homes are less efficient than multi-family. Small town doesn’t have all the services so people drive to the Walmart or hospital. Or city if they need something special. The same housing in Arlington is super efficient. Tear down house, build apartment building. Connect to sewer, roads, etc. The residents walk to the Metro stop. A lot of the small town problems also apply to sprawl and exurbs. It is possible to build more efficient small towns, older ones have a walkable core.
