If you got rid of cookie cutter buildings because they might be fraught then you'd have to condemn most of nyc and most of london. The home era boom these articles all cite came because they were just churning out the same floorplans or more or less the same buildings with the same materials all day. In the US you could even order one of these standardized homes from the sears catalog, have it shipped to you already cut and build it yourself or hire a contractor who does these same homes all day. I really believe we are letting perfect be the enemy of good here, and saying we'd rather tolerate things like people living in overcrowded tenemant conditions or in cars or tents, because that's the status quo today for many of the working poor with these prices, over potential unknowns of reusing a building plan.
