As I understood it, there is an extreme on only one side. One side
says the current through a loading coil doesn't change. The other
side says that the current through a loading coil does change.
You can look at the decrease in the feedpoint impedance of a loaded
antenna Vs a wire antenna and prove that the coil doesn't exactly
replace that length of antenna. The coil is a more efficient inductor
and less efficient radiator than the wire it replaces which results
in a higher net current at the feedpoint. To the best of my knowledge,
no one has said there is an exact 1:1 correspondence between the coil
and the wire it replaces. The correspondence is only approximate.
