What is the problem?
In our carrier we always have 121.5 tuned on VHF 2.
We are grown adults so when the radio gets annoying WE TURN IT DOWN A BIT UNTIL THE IDIOTS STOP CHATTING.
Don't forget that all ATC units have the ability to transmit on 121.5 if they need to. Plenty of crews have been located this way and I'm sure a few received landing clearance as well.
So in my opinion it's good
Airmanship to listen out on 121.5.
It's not rocket science people for gods sake...
