I explained why it only applies to coherent
waves. Every model has its limitations, even
yours unless you are presenting a theory of
everything.

Given that optical EM waves are only capable of
solving a subset of the uses of transmission lines,
it is not obvious why I should study them when
I can invest in learning approaches that will do
the whole job.

That's not a given and is in fact a falsehood.
RF waves are a subset of light waves. Perhaps
you are erroneously confusing "light waves" with
"visible light waves".

When a light wave is red-shifted to 10^12 times
its original wavelength, does it cease to be a
light wave? Feel free to answer yes or no.

Well, others more knowledgeable than I in optics
have disputed whether *your* approach accurately
represents those described in the textbooks.

The last resort is an argumentium ad verecundiam,
an appeal to reverence/authority. Who, in particular,
do you consider to be the High Priest of r.r.a.a?

The technical truth will win out in the long run.
