But the only electric current on the molecular level is coherent current...? Chemical reactions are not macroscale phenomena, and so it shouldn't really matter if the energy comes from a random distribution or not. Also please don't insinuate that I'm "profoundly ignorant", that certainly isn't relevant to the discussion.

Profound ignorance is insistence of certainty in the entire absence of knowledge of a subject.

Microwaves absorbed in tissue induce electrical currents carried by ions in solution. Just about everything that happens in your body involves ions moving in solution, one way or another. Details matter.

But the movement of ions in solution is almost completely dominated by thermal motion. Your signal doesn't matter if the signal to noise ratio is essentially zero.
