I would consider consumer electronics to be discretionary purchases. So what I suggested is the opposite of that. If disruptions are an acceptable risk, then you should prioritize efficiency. Consumer complaints are meaningless if they don't have a viable competitor to shift their money to.

But we must prioritize resiliency when an economic shock would result in societal instability. I'm willing to pay more for food to be available 100% of the time versus paying 20% less for food to be available 80% of the time.

Human experience simply cannot be averaged over large spans of times while ignoring the extremes. Dipping into the red means permanent damage. Imagine applying this line of thinking to your bank account -- "sure I spent $500k in two years on fast cars and fancy bars, but averaged over 80 years of paying small amounts of interest, the bank should be glad to make the sacrifice of stability in favor of efficiency."
