I also disagree with the notion that a commodity-based money equates to a barter economy (if I understand the article correctly). An actual exchange of gold for food is indeed barter, but as soon as loans are made you have the creation of new money that isn't gold. The original "bank notes" were effectively IOUs issued by banks; hence the "promise to pay" language on them. But they promptly became money, exchanged just like the gold they supposedly represented.
