What I am getting at is if these “proofs” existed, they would already be proven by lower priced goods at the market.

A historical existence proof of a system or technology working has essentially nothing to do with whether it's being practiced in industry today, and whether it's being practiced today has very little to do with the product or pricing you see when you for example stop by KFC to eat a piece of chicken that's largely created out of corn, soy, and methane. That's the beauty of capitalism and commodity markets, John Deere can roll out technology for say computer-controlled planting that improves efficiency and the dividends get spread across the value chain without everyone having to know about it or change what they're doing.
