Yeah, that narrative isn't new; its being covered in various documentaries and books, including this cartoon [1] Harari gives very good examples of how money is useful for trade in his book. These examples underline how money is useful for trade. Its downright impractical to trade goods for goods because of multiple factors: fluctuation of value, different values for different people, lack of preference of the item from one of the parties. Perhaps there was not one reason why money is useful. There surely isn't one now. [1] https://www.youtube.com/watch?v=4AC6RSau7r8 https://www.youtube.com/watch?v=4AC6RSau7r8
