I often wonder this myself. I also wonder where the technology would be today if the world was allowed to freely develop these early technologies for the last 100 years freely. If Henry Ford's Model T was made from hemp and it was 10x stronger than steel back then, where would that technology be today? If his Model T ran of hemp diesel back then, how efficient would that fuel production be today if it was allowed to progress? We'll never know, I suppose, but it could have led us in a direction where we aren't trying to fight (be taxed) for climate change and the green tech could probably have been developed sooner.
