Actually, Daoshen did stop to consolidate around 3145, per... FM3145. That's when he reorganized the coreward commonalities, etc. The problem was that he just could not let go of his revenge fantasy against the Republic, which entirely fits someone with his psychological profile, and decided to just keep going. Never mind the CCAF already having had to deal with their conflict with the FedSuns on top of his mad dash to gobble up the Republic. And unlike Sun-Tzu, Daoshen is a lot less likely to listen to any advice that runs contrary to his own wishes.
Honestly, the Ravens probably did the CapCon a big favor, because it is quite likely that Daoshen would've ground the realm into dust.
