Would you care to elaborate on the idea that "energy is being used to
transform impedances"?


If reflections are nonexistent, no transformation takes
place, i.e. there is no SWR circle, just a point at the
center of the Smith Chart and the system is flat.

If reflections exist, then the superposition of the
forward wave and reflected wave transforms the
load impedance to some other impedance on the SWR
circle.

A 1/4WL transformer, for instance, will not transform
unless there are reflections present.

You fail to explain how any of that makes energy unavailable for
"radiation purposes".
