Why do you believe the "net" current somehow has different properties

Because the net current is a *STANDING WAVE* made up of equal magnitudes
of current flowing in opposite directions. That makes the net current
zero, Gene. Standing wave current doesn't flow. The RMS value stands still.
Standing waves are only an artifact of the superposition process. Everything
that needs to be known involves the two traveling waves that cause the
standing wave. Asserting that standing waves flow into the bottom of a
loading coil and out the top shows a complete ignorance of how standing
wave antennas really work. After that false premise, none of the
associated conclusions are valid.

Standing waves are not static.

The RMS value of a standing wave at any point is indeed static.

The current may not "flow", whatever that
means, but there is certainly real non-zero current at every point
except the exact nodes of the standing wave. If you prefer, the standing
wave current oscillates rather than flows, but that is of no special
importance here.

It is of infinite importance. If the standing wave current oscillates in
place, it doesn't flow through the coil. W8JI says it flows into the bottom
of the coil and out the top. Nothing could be farther from the facts of physics.

Why do you believe standing waves are somehow inferior to traveling waves?

Standing waves are an artifact of the superposition of two traveling waves.
Standing waves have a constant differing RMS value at every point on the
transmission line. Traveling waves travel and have the same RMS value all
up and down a lossless transmission line. What is it about that concept
that you don't understand?
