The kind of density you get in European towns built in the 1890s were higher than the typical SFH or 4 story max zoning limits in many places experiencing housing crises today. If SF was rows and rows of 6-8 story buildings instead of being %50+ SFH, it would have a lot more capacity than it has today.
