I understand your point. But arguing that energy changes direction
without reflection, dispersion, or diffraction is an attempt at
inventing reality.

I'm not arguing that at all. In a transmission line, destructive
interference causes an energy reflection in which the ratio of
the E-field to H-field is transformed from one characteristic
impedance to another. It's all described on the Melles-Groit
web page. They don't call it an energy reflection but that's
what it is.
