To be fair, bearfoil, there is one more consideration I'd hoped a pilot would chime in and talk about. 121.5 MHz is an emergency frequency. Using it for idle chit-chat is or should be quite a downer to one's career. However, my reading of being out of communications is that it's a minor emergency sufficient (barely) to qualify for use of that frequency.
I hope somebody "real" chimes in on this proposed use of the emergency frequency if it's inappropriate use. (And it arguably is more appropriate after this example of what can happen when one is out of communications; but, could be.)
