I mean, it's literally a coordination problem. Redundancy and resiliency rarely decrease costs in normal operation. If you're operating in a vertical, and all your competitors are operating diverse/redundant supply lines, you are at a tremendous advantage to defect and slim down. It's only when disruptions become frequent enough to model in a straight forward way (and also frequent enough to loom in people's memories) that we can expect a pure market solution. The same way tech companies rarely actually go for multi-cloud setups. Our primary system of incentives are not setup to consistently deliver black swan redundancy.
