I can’t recall anyone lobbying for more waste. Maybe people in the junk business, but that is another matter.
The problem with efficiency when applied to manufacturers, supplies, warehousing, deliveries, etc., is that all redundancy is wrung out of our system. Thus the supply chain shocks we’ve seen during the pandemic have revealed themselves and the shockwaves continue to ripple through our economy.
Duplication and redundancy are many times seen to be one and the same. However, it is duplication that is bad and redundancy that is good. Having some flex in the supply system allows for minor disruptions to not become major ones, say in lumber or microchips — or even personal protection equipment (PPE).
