The purpose of a transmission line is move RF energy from one place

But a balanced transmission line creates two electromagnetic fields
which cancel one another, Shirley?

What is the value of a canceled check?

You mean a cancelled cheque? :-)

If a balanced transmission line created an electromagnetic field, there
would be losses in the line as the line is the only source of energy.

Again neglecting I^2R losses.

What about losses due to imbalances - for example, coupling into nearby
conductors due to poor installation, which presumeably derives from
either of the two electromagnetic fields which aren't generated? :-)

PS - sorry about the Subject line. I'm sure you know who's responsible
for that.
