Iron pans, store in glass, butter, lard. If you spill stuff on a couch just live with it. Buy leather. Too many things are made because people are lazy. If you have kids don't have nice stuff, it's very easy.
An unexpected upshot is that in a functional household you can let them play like actual children, without the cloying anxiety and constant shrieks of "For Gods sake Tristan and Tarquin, not on the Louis Vuitton !!"
(Myself I prefer the approach of "have nice stuff, just don't sweat it when kids damage it - it's still just stuff".)
Also, your point doesn't work in context of GP's comment taken as whole, i.e. of reverting back to products used 50 years ago: a big value plastics bring as a material family is safety - when you replace your plastics with glass and metals, your home doesn't turn into a "functional household you can let them play like actual children" - it turns into a hazardous environment where children can maim themselves with every other object they touch.
Like, the other day my 14 m.o. accidentally dropped the bottle she was drinking from straight onto her foot, and cried for a minute. If that bottle was made of glass, we'd have to take her to a hospital for an x-ray.

Trying to avoid this stuff is a bit like Night of the Living Dead -- it's everywhere.
