I am not saying producing is not important, my point is that you cannot just demote consumption to an unnecessary side variable, because even when you trade your surpluses, you each are the market for the other.
Does that not make consumption as important? What if no one likes fish other than the one Asian? What happens in that scenario?
If no one likes fish, then fish are not "supply." They are waste from an economic standpoint. Toyota famously took this view, that over-supply is waste. Their just-in-time production was designed to eliminate this waste.
