On my first read of this, it makes sense though. The mileage of infrastructure is the same regardless of use. Those powerlines still need maintenance even if LEDs are making homes more efficient.
Burgers and bread loafs compete on all their costs, different competing outlets actually differ in those costs, and people choose which ones to use.
Utilities don't have that. Everyone is stuck paying for both infrastructure and use, so it makes sense to charge them separately.
If each neighborhood had exactly one restaurant that everyone used for all their food, maybe it would make sense to split the burger flipper costs evenly.
