The History of Non-Cash Industries Trading With Each Other

There are some quite baffling details in TraumaZone, your documentary series. One of them was non-cash industries trading with each other using an artificial currency that then, called the Kofsky, who was the first oligarch, turned into real money. Can you, in the remaining minute and a half, try and explain? I tried to. It's very difficult to explain. Basically, if you have everything planned so that I'm going to make a car for everyone, including you, I don't need to make a profit. So, therefore, money in its traditional sense is irrelevant. What you simply need is some accounting measure between factories and suppliers and things like that.
