There’s a lot of comments posting personal preference in housing, but that’s basically irrelevant. Density and urban planning basically comes down to freedom.<p>How much freedom do we allow?<p>On one end of the spectrum, the fully suburban city (like your average American city) allows virtually no freedom. As land value rises, you hit a maximum density (prescribed by minimum lot size, maximum height, minimum lot setbacks, parking requirements, and maximum number of housing units) and this becomes the shape of the city.<p>If you allow more freedom on some or all of these dimensions, then as land value rises developers will purchase lots and infill or redevelop.<p>The rest of the city stuff that urbanists talk about (trains, bike lanes, parks and walkability, etc) all become increasingly valuable to everybody as density goes up.<p>So the options are freedom or suburbs. Many Americans prefer suburbs, which is understandable. The American suburban dream is a beautiful one, but undoubtedly built to suppress freedom (from inception: a way to allow middle class white people to escape the minorities and poors of the city in post-war america, keeping them away through redlining first and then by stringent zoning and expensive housing later)
