This is directly analogous to the buffer bloat problem. Smaller inventories and more responsive suppliers means better communication of intent and supply in the supply chain and therefore greater efficiency and prices. Why are advocates of big redundant inventories willfully ignorant of this?

If we optimize for efficiency, we get supply disruptions every 5 years or so. If we optimize for redundancy, we suffer from higher prices all the time, and delayed availability of all new tech. I don’t know which is worse.
