Most people don't build houses. Most people buy houses that other people build. Therefore, most people don't care that the houses other people build are "McMansions".
Most people don't make clothes. Most people buy clothes that other people make. Therefore, most people don't care that the clothes other people make are (random style out of a hat...) "punk".
I don't think this logic adds up. People care what the house they buy looks like, and some people even care what their house's appearance projects as an expression of their own taste.
Have you visited a menswear blog or forum recently? It's the same sentiment. "How could you buy a dress shirt that's not 100% Egyptian cotton with perfect hand and pattern matching with fabric from a 200-year-old Italian mill and hand-stitched by this guy I know in rural Siam!?"
People don't close their eyes when the buy houses, but neither do they have an eye for architectural nuance.
