You are so right. Though I would perhaps even go farther, saying there is no value without an underlying extractive or raw good, such as oil, metals, and including crops and forests and beasts and fish, wild and domestic. And probably even wind and sun, among other natural materials and elements that I can't think of here.
Without the raw good there is no product. Without the product there is no exchange. Without exchange, there is no profit, no added value, no refinement, no advancement.
Of course we all live so far from those facts now...but facts, like the laws of nature, will assert primacy at some point.
Am I wrong in this?
Absolutely not; that was implicit in my comment. But you are correct to highlight it.
It's why I laugh [well, smile sort of] at those who tout the information economy. Now, information is very important -- but it is only economically productive when it is used to make the process of turning raw materials into finished goods.
Without that, it's just, well, Facebook.
