This is incorrect.

Quite the opposite in fact, when after 9/11, we were reminded to
monitor this frequency since the military will be calling us during an
interception.

Airlines DO monitor it! You should hear the number of times Jet Blue
or United try to get a "push back" from the gate on 121.5!!!...:-)

Single engine are also supposed to monitor it. Every month I hear the
Air Force trying to get a heads up to someone who is about to enter a
restricted airspace...
