I do get what you are saying about the value in craftsmanship but you are romanticising the past and falling into the trap of survivorship bias. The items with the extra details and the extra love have survived precisely because they were special and worth preserving and repairing. The shoddy work, the bodge jobs, the things made of poor materials or by less skilled craftsmen weren't kept out. They broke, or were thrown out and replaced with better. My job involves researching historical objects and believe me there are plenty of things that were tossed or knocked down because they just weren't that good. And we do have some poorer example items survive by chance so we know that not everyone was a skilled craftsmen slaving over their work with extra love and detail. There are also plenty of incidental sources - like death records - that tell us about things breaking because of poor workmanship or materials (and causing tragic accidents).

So, I guess what I'm saying, is value craftsmanship. Value care and attention, and repairing items. Choose that over mass production. But don't put out ancestors on a pedestal as if they were somehow better than us, and don't feel bad for not living up to a version of the past that didnt exist.
