How does inserting a circulator load into a circuit that doesn't have
one illustrate anything about energy flow other than the behavior of a
circuit with a circulator load in it?

Do the reflected waves that you see when looking
at yourself in the mirror contain any joules/sec?

You seem to be laboring under a misconception about my point of view,
Cecil. But it can't be for a lack of attempts on my part to persuade
you of it.
