If you could teleport oil, grains, or manufactured goods across the internet for much lower cost than shipping them in the physical world, that method would eventually be adopted and eliminate the alternative.
The history of celluloid film is probably the most instructive. The studios used to spend millions of dollars every year manufacturing 35mm prints of their movies (~$50k/each!) and shipping them all around the country to be exhibited. They didn’t stop because this didn’t work, but because an alternative was developed: digital exhibition. Suddenly they could accomplish the same thing for a fraction of the cost in money and time. And within a decade, this multi-million dollar sub-industry vanished. Kodak, once synonymous with the photographic image, totally missed the boat and is no more.
It’s not that you can’t ship gold around the world for international trade, it’s that it is cheaper and easier to use fiat. And it’s even easier and even cheaper to use Bitcoin.
It took a decade to go from Blockbuster’s best year ever to bankruptcy.
I suspect the next decade will see a real phase change in money, for the same underlying technological reason.
