The limitations you describe make sense. But they seem like we can overcome them.
My home has 3 non-plumbing busses: AC to every room. Twisted pair to like 6 rooms that will never see use. Coax to 7 rooms that is only used for a modem in one room.
If we can run all that wiring, I think we can introduce a new standard for upcoming homes.
In fact, now that I think of it, my home has a trait that the homes I grew up in never had: the overhead lighting and the wall receptacles are never on the same circuits. ... I wonder if I can re-use the 14-2 Romex for DC and retrofit one or two rooms myself and see how it works? (I recognize this is a bad idea for many reasons, such as them being indistinguishable and wrongly colour coded, making it a dangerous trap for future owners).
