You say this like it is a law of nature, but we can plan and build it directly if we want it. Redundancy is not something that only emerges from an indirect 4d-chess strategy of ownership mixes.
Exactly — if we want redundancy, we should plan and build it.
That’s why I offered one possible implementation as a hypothesis, not as a law of nature.
If you have a better non-ideal, real-world design in mind, I’d be interested to hear it — it makes the discussion much easier.
Good point. For example, the TVA and BPA are federal agencies that produce electricity. Clearly publicly owned utilities can be successful.
