I think you may be conflating commodities (and real estate) with the concept of "store of value". Those can be stores of value as well, of course. But using your explanation, doesn't it also take resources to create baseball cards, art, books etc., yet we accept they can be a store of value.
And with most stores of value, there is no guarantee you will get out more or equal to what you put in.
