I think we are talking past each other. When people talk of a copper shortage they are talking about copper that has been mined, processed and is ready for sale to those who wish to purchase it. They are not talking about copper ore that resides hundreds of metres under the Earth. The former is useful, the latter is not although may be in the future once millions of dollars has been spent digging it out of the ground and processing it into a form that can be used for industrial production.
Copper below the Earth is plentiful, copper mined and processed is not necessarily so. Copper mines take many years and mountains of capital to plan, build and then operate.
