Agree with all of your post up until here. Mutually beneficial trade can exist through exchange of equal amounts of wealth. Trading wealth in the form of money for raw materials to do work can be useful for both the producer of raw materials and the manufacturer. The manufacturer reduces their store of wealth to acquire the capacity to do valuable work, while the miner sells their end products increasing their store of wealth. This can easily be mutually beneficial trade under an idea of money as a store of wealth.
