CM DC steady-state does not cause electrons to emit photons.
CM For RF photons to be emitted from a copper wire dipole, the
CM free electrons must be accelerated and decelerated. The DC
CM component cannot accomplish that feat.

Very true on the macro scale but even a DC potential becomes
discontinuous at a microscopic level. Remember that there is a
distance between atoms, electrons, molecules and are not continuous.
How is it done except if not by photons, virtual or otherwise, whether
the context is AC or DC?
