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.
