And how do you compare metric tonnes of steel produced, with metric tonnes of plastic produced? What about metric tonnes (hours?) of entertainment on films?
The metric to measure value using quantity of goods must use a common denominator unit, otherwise, comparison becomes subjective (one might want to value tangible goods more than intangibles for example).
So making comparison using a price makes a lot of sense.
