I explained it already. The current maximum in a loading
coil is caused by the magnetic flux linkage between the
adjacent coils.

Yes, you did say that, but it isn't apparent to me that the two
statements are necessarily mutually exclusive. To me those things are
all interdependent. Insofar as constructive interference is caused by
reflections from discontinuities and not the other way around, then
yes. But the current maximum is simply an area of constructive
interference. It is the profile of a standing wave in 2 dimensions
caused by the superposition of forward and reflected waves. The phase
and amplitude of the forward and reflected waves are of course
determined by the nature of the line, and those parameters determine
the profile of the standing wave.

It is the same thing that approximately
doubles the velocity factor of the coil over what it
would be if the all the current followed the wire.

I think current is required to follow the wire in any case. :-)

The distance between current anti-nodes is 180 degrees.
All the lack of apparentness in the world will not
change that fact of physics.

Such insight is incredible to behold.
