And what about the "displacement current?

If Maxwell had known about photons, he would never have invented
displacement current.

Assume we have an ideal transmission line terminated in an ideal
capacitor with two plates. It's easy to prove that the displacement
current flowing from one plate back up the transmission line, through
the source, back down the transmission line onto the other capacitor
plate has to be traveling much faster than the speed of light. Does
that give anyone pause to question the very existence of "displacement
current" in reality?
