You've got the reference to the Chief Counsel's opinion on this? Please
cite URL so I can read it for myself.

You can look up your own Chief Counsel opinion, or better yet write them
yourself. This has been discussed numerous times here. On one recent
instance, Jim Burns posted a number of relevant entries from the
quasi-official Part 61 FAQ. You can find that post he

The FAQ quotes the FAA from the preamble to Parts 61 and 141, which reads in
part: "With respect to the holding of medical certificates by a flight
instructor, the FAA has determined that the compensation a certificated
flight instructor receives for flight instruction is not compensation for
piloting the aircraft, but rather is compensation for the instruction".

It goes on to explain the various regulations, and why all this means you
are not exercising your Commercial Certificate when instructing.
