Rather than two separate pools, I see it more as that every good's value is a complex number. The "real" part is the sticker price and the "imaginary" part is the time spent to consume or enjoy the good. So while we usually just assume the sticker price is the value of the good, in reality you have to calculate the length of the complex vector.
When you're young and poor, the sticker price seems very close to the actual value, but as you get older and richer, you come to see the time spent as by far the most significant scalar quantity.
