This was under the assumption that the transmission line was at the same
voltage as the end-user, because there were no good DC-DC voltage
converters in that day. And a few bazillion amps at 120V needs a really
fat wire.
There's no significant wire size difference between a DC and AC line at
the same ampacity.
Voltage conversion is the key. _If_ you can do it, then transmission
isn't a problem.
