Which come from where? Last I checked there weren't many pump jacks in Copenhagen.
Pretty much all material wealth of modern society comes from raw materials sourced in rural areas. Those then get processed locally (e.g you don't waste money shipping logs, you mill them and ship boards) and post processed in increasingly urban areas. It's the paper pushing (engineering, finance, etc) of the supply chain and distribution that tends to be centered around urban areas.
I hate these sort of macro-economically ignorant takes and their peddlers. Acting like either part of the economy could exist in anything like it's current capacity without the other is an exercise in lying with numbers to obfuscate the lies.
Cozy small time agriculture in the west is a small part of your general food supply. The rest is in places you do not want to live and is called monoculture.
All "raw materials" you mentioned are not produced "in the countryside" in either Denmark or most of the West.
It all starts with oil and energy. Nothing else matters as much. So getting off oil and producing energy in other ways is at the forefront of our struggle as a species and if you deny this progress because it hinders the view from your detached house porch I get the impression you have not really realized the situation we are in.
