Resource hunger is not just about ore, metals or energy - it’s about people too. When the cost of everything goes beyond any limits, there is no time for concepts - here you would have to figure out where to get resources for the production of artillery powder. And how to build a factory for shells, with which there is already a huge shortage, if the municipal authorities of one of the German towns decide that instead of a factory it is much more appropriate to build a park for local people - and this is democracy, you can not argue here.
