Yes, the issue with that though is it is used in very advanced conductors. The kind of conductors that can only be produced in advanced factories by advanced large societies. If a collapse actually happened how do you fancy that factory works exactly? You gonna run a conductor factory to sell those conductors to who exactly? The potato farmer you are trying to convince to give you potatoes for that very same gold?

Low grade electronics that would be valuable in even a simpler smaller community like basic generators and light bulbs use exactly zero gold. Copper on the other hand is needed for almost all of that
