Me thinks that you're stretching the discussion......
I accept that there are circumstances where you need to adapt your philosphy a little.
Now, I'll stretch my point a little ..... if every aircraft that was lost/uncertain of position went 121.5 / 7700 at the first moment they aren't exactly where they think they are you'd have every training detail and, I suspect a fair number of PPL pilots on frequency within a short space of time.
