I get the intuition behind fully socializing it, but I wouldn’t go that far. Single-operator systems lose redundancy fast, and that’s dangerous for infrastructure.
A layered mix — county-level public utilities, some private operators, and some hybrid/municipal entities — might be closer to a resilient structure.
Not clean or elegant, but fault-tolerant.
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.
