>It would be wise to have multiple sources for any given good, especially if it's essential. Redundancy is in direct opposition to efficiency. You're always going to move faster and do it cheaper building a singleton, in the non-digital world where there are real costs to duplication. In driving towards efficiency, redundancy presents no immediate benefit, introduces measurable costs, and so is actively selected against at every stage. I'm not saying this should be the case. The drawbacks on long time scales are... well, exactly what we're seeing right now. But it does explain the current situation.
