You're continuing to make good arguments for why mass-production should exist _alongside_ artisanal craftsmanship. Broad availability of housing which is functional, albeit of questionable aesthetic appeal, is a good thing to improve housing availability[0];
and also it is a good thing for (fewer) well-built, charming, individual homes to be available for those who want to spend more and to get more.
[0] I'm extremely aware that there are other contributing factors to housing shortages. Tax Billionaires, etc. My metaphor still works despite not being total.
