That would only be a naive perception on your part. Perhaps it is part
of your misunderstanding?


All waves deliver energy somewhere even if it takes forever as in the
case of the detected background radiation. In a lossless transmission
line, all waves deliver energy to the load (and possibly to the source
after power to the source is removed).


So your claim is that energy is delivered by two waves that are equal in
amplitude and opposite in phase?

There is no such thing in reality as a wave that delivers no energy.


See Born and Wolf for examples.

Waves cannot even exist without energy.


Correction. Waves cannot be created without energy. Electromagnetic
fields can indeed exist without necessarily conveying energy from one
place to another.
