When you have commodity money, the value of the money is derived from the value of the commodity. You don’t get to assign arbitrarily higher values to the money because the market determines the value. But yes, all speculative assets typically have a higher extrinsic value compared with their intrinsic value but I don’t believe that has anything to do with it being a medium of exchange or not. That is just supply and demand.
