Currency was one of the most useful social tools humanity had invented. It emerged from the process of commodity exchange, separating itself from the world of goods as a commodity that permanently served as a universal equivalent. It was the product of commodity exchange.

And the clothmaker might not need grain either. Society was a complex system; if they kept searching like that, no one knew how complicated and troublesome it would become to complete a single transaction. But the birth of currency simplified the process.
Once producers throughout society recognized this universal equivalent, it could be exchanged for as many things as possible and truly gained meaning. Otherwise, whether it was gold or paper currency, if no one recognized its validity or value, it could not be considered money.
