Please note above that I said wave interference indeed *can*

the redistribution of energy. Wave cancellation is a special
case of wave interference in which the waves *cease to exist*
in their original direction of travel. The conservation of
energy principle dictates that the energy contained in those
waves before they are canceled, must necessarily be redistributed
along a different path. Note: Any different path in a transmission
line is necessarily the opposite direction, i.e. a reflection.

All correct - neither proving your point or disputing mine.

The thing you really need to consider is: how much energy is actually
"in" a wave (whatever that means) that delivers no energy.
