It's possible to have complete, walkable communities where most people live in single family homes - streetcar suburbs. It's also possible to have totally unwalkable multifamily housing - very common in some postwar sprawls to build a subdivision off an arterial and fill it with townhouses or condos. These can even look like good urbanism in carefully framed photos. It's only when you zoom out that you realize it's just the townhouses surrounded by "open space" and fast roads. The issue with suburbia is the framework, much more than the housing types. The battle over housing types is more about within existing city grid systems, doing some piecemeal replacements of single-family houses to duplexes, triplexes, and apartment buildings. Suburbia produces multifamily housing easily enough - not that much objection to new condo/townhouse subdivisions. We just don't celebrate that much, because they are still ultimately subdivisions.
