"Without doing anything?" You mean...without exploring the bubble before anyone else? I don't see the problem with rewarding players based on how useful their efforts are to other players...
What usefulness? what makes these players more useful compared to all the other players who also charted and sold the same exploration data?
What about all new players who at the current state of the Galaxy can never get this reward, as all the core systems are already being mapped and tagged by other players. Sure they can go out a few hundred LY of the beaten path and tag their own systems, but noone would ever buy this information it is too far away from any station...
I fail to see why we should implement anything like this. As this only would be beneficial to the early adopters who could map the bubble first, now it is all mapped.... so no new discoveries in the bubble...
