Wrong. Demand for hand sanitizer increased because people thought the world was ending and hand sanitizer would save their lives. Hand sanitizer went from a tool that marginally increased your health to a tool that many believed would save their lives. If you can't call this a genuine rise in demand, I'm not sure what you could call a rise in demand. I haven't seen any real data that the effect of middlemen was anything but tertiary. Hospitals and governments buying up truckloads of hand sanitizer had a greater effect on the market than middlemen.
