> You could get the current 1800W of energy out of a branch circuit with 15A at 120VDC and all the limitations/massive wires I described.
15A at 120VDC wouldn't require massive wires. I'm not sure why you think it's drastically different from 120VAC for wire sizing. If dropping 10% of the AC voltage is OK, dropping 10% of DC is presumably OK, too, and either is I * R. About 96 meters to drop 12V, or 48 meters out and back.
It's not a good idea for plenty of other reasons, but...
