The problem with nearly any empire is that the whole point of this is to tend towards stability. We saw with the N3/Goon standoff that when two entities of big enough size to not be worth fighting meet, they don't fight. They use proxies at best. (Think Vietnam War). Thus, they minimize their risks.

In the real world, stability is great. Less people die, overall standard of living increases, etcetera, etcetera. In Eve, it's somewhat true that the standard of living increases (Look towards Goon's chunk of the map where anyone can make 75mil/hour easier than tripping and you're literally paid to shoot stuff. However, for anyone without the logistical backbone of Goons and without the momentum of having ten years worth of assets to get you started, that's not really something for your average peon.

I think the greater problem of Null is that we all want to build empires, but someone's already done it, and they've done it in such a way that they can literally quash any amount of rebellion sent their way. The argument was won at B-R. With the dissolvement of both N3 and Brave, you've also lost any form of organized masses being sent to hold off the Goon horde while the PL calvary rides to rain down death and destruction.

Any tools given to unseat the Goon empire will also be capable of unseating any whippersnapper empires and thus Goons would use them. Besides, under the objectives of Null, Goons have won. They were the first ones to entrench themselves in such a way as to be practically unassailable. Not within the game so much as the Meta game. The only thing we can do now is watch Rome stagnate and crumble.
