What you described is logical and is an answer that would partly make sense.
But that doesn't really explain why Q keeps saying things like "You have so much more than you know", and prompting us to "Continue to build the MAP", and warning us "You are missing the connections."
He apparently wants us to take action from our end towards an important discovery we can achieve, that is also realistic for our level of access.
One the one extreme, hopefully he's not just making us feel important, and keeping us busy, though he knows we can't really do much from our end. And on the other extreme, surely he knows we can't build up complete cases that would be on the level of what is filed in a court of law.
It sounds like you are completely certain about your viewpoint though, and have spent time thinking about it. So I'm not trying to convince you otherwise. Just thinking out loud.
