I think anyone CAN make a good stool like that if they can find the materials and some hand tools, it's just that nobody can be bothered and nobody wants to pay someone to put in the effort. Or that nobody has access to tools and/or a space to do the work. There does seem to be a bit of a renaissance in woodworking though.
1. germinate new oak trees from genetic material recovered from lucky stool (1-20 years, say) 2. tend to trees as they mature (40 years) 3. fell trees, craft new generation of stools. (~1 year) 4. use stools until only a handful of lucky stools survive (500+ years) 5. iterate
if all goes to plan, by year 2600 or so the third crop can be underway
