It's an inevitablility I think as standardisation solves a lot of problems such as costs, ease of troubleshooting, etc. Most importantly its is the first step to automation. Your right nobody wants inferior housing even if it's cheap. The challenge is to provide quality housing that people want to live in that has this standardisation. It's a big ask, starting with cheap housing then improving scale, quality, etc is the first step. Eventually it will catch on.
