I think you’re right to some degree… In the video he does briefly mention that there will be a danger of crashing the market for certain commodities like gold and platinum.
But I think it’s the super rare-earth elements that would be so valuable, assuming they have a transformative potential for earth industry… Consider if a vast supply of some super-rare element suddenly became available and this element happens to become indispensable by enabling technology vastly superior to current technologies… It could create a situation like oil did in the 19th century. Like if they found some element that could make high-capacity batteries cheap and ubiquitous… Or for some kind of new supercondutor on the cheap.
There’s a lot of “what if” in this scenario, but the video makes this enterprise seem like it’s going to happen in the next couple decades… I highly doubt that. I think this kind of enterprise is a century away, especially for the more elaborate stuff.
