Right now, it's a little too easy for the game to fail to generate any CSCs except for the plot-required ones. That in turn means that there's no way for the player to get Fleet ranks, which prevents them from interacting with those plot CSCs (and Point Juno) in any really meaningful way.
What if destroying Ares Communes, and especially Ares Shipyards, was an alternate way to get Fleet rank? It'd be similar to how destroying enough Sung fortresses makes the Huari happy. There's always plenty of Ares stations available, and they're at least as hard to take out as the Fleet missions are to do, possibly excepting the mission that pits you against a Phobos.
I wouldn't grant rank for taking out Ares Outposts, though; those are too easy.
