Harmon, not to mention that in order for that defence grid to be effective at all, you would need to put warp disrupters denieing the entirity of the inside of the oort cloud to people coming it. Otherwise, your MAC's are basically useless. It would take CENTURIES or DECADES to hit anything in the solar system with those MAC's, most likely the latter. Even a laser would take 6 months to a year(depending on if the oort cloud is 1ly in either diameter or radius) to reach anything in the solar system unless traveling via warp or going at superluminal speeds by some kind of warp accelerator thingy. And if you were to use warp on them to allow hitting things in the solar system... Not only would it be super exorbit, it would be more expensive than the warp disrupters by a large margin. But yeah, if there is no warp disrupters disrupting the entire oort cloud, the Sith and any other thing trying to get to earth can bypass your defence grid entirely because they can still warp through.
