I honestly think the author made a pretty bad point. Time isn't money. Instead money is a construct that is very useful for the exchange of goods. Sure, part of the argument for a price is time, but the agreed upon price is not an expression of time alone, but mostly supply and demand. That's why you are more handsomely awarded for making things that are actually in demand, and thus valuable for the other party. But sure you can measure just about anything as a "cost" if you like. Personally I find a lot of work quite enjoyable, though. So is it then a "cost" for me to endure it?
