We won’t get anywhere near net zero. The point there was that 700M tons of copper has been mined in the whole of history and it would require 1.4 Billion to accomplish it. So even if they got it to the 30% mark it would still be a helluva lot of copper, and then a slew of rare earths which we don’t mine in the U.S.
I still think money gets attracted to real goods at some point in the near future if nothing else as a hedge against inflation caused by the falling dollar.
