Then someone always follows such a recommendation with the news that
with 240V you can run smaller wire. Smaller wire was the problem in
the first place (at 120V). If you run smaller wire at 240V, you have
essentially put yourself right back into the same circumstance you
were before.

Look at it this way: To get the same behaviour at 120 that you get
at 240 with (forex AWG12), you'd need to go to AWG10 on the 120
circuit (and possibly a 30a current interrupting device, to boot).

So, you can use smaller wire with 240 than with 120 _performance being
equal_.

I do understand your point, however.
