You don't know that the rapid inflation and deflation relative to today isn't because of poorer coordination in the liquidity of markets, in the supply chain, because we didn't have airplanes we didn't have computers etc. It's like pointing out that people were starving in the streets during the depression. Well yeah. We didn't have modern agriculture, freezers were a luxury, Flintstones gummi vitamins weren't a thing for kids etc.
