It's not a new requirement, Gene, just a very old requirement of
physics. Photonic, i.e. EM waves, do not flow back and forth as you
are implying. As long as the medium is homogeneous, i.e. doesn't
change, a photon travels at the speed of light in one direction in a
medium. So yes, net energy flow is absolutely a requirement for
photons.

EM waves *are* photons and do not vibrate back and forth in a medium.
They travel in one direction at the speed of light in the medium until
they encounter an impedance discontinuity. Virtually any physics book
with a diagram of the EM wave E-field and H-field will show the
direction of travel as one direction without the "one step forward and
one step back" concept that you are proposing.

You claimed that standing waves cannot be real waves because they cannot
obey photon rules. I easily demonstrated that idea is incorrect.v

All you demonstrated was your ignorance of the nature of photons. Your
analysis was incorrect. You are seeing the standing wave illusion and
assuming an impossibility of physics. It is very clear that you and
others simply do not understand the nature and physics of photons and
photonic waves.
