There is also the problem of knowing WHICH key to use (ie: Even when you know the message is intended for you, you must do a test run with each of your keys until one works).

I believe that provided all your keys are in your secret keyring, PGP will automatically pick the correct one for you.

I know that. The situation was that the hypothetical message format itself contained NO INDICATION of who is was for or what key was used to encode it. PGP selects the right key by using the indication that is in the message of what key is to be used.
