Supposing Stargate technology exists, you could conceivably control an entire galaxy, but that is proposing the existence of technology incompatible with our best understanding of the universe. Realistically the solar system will probably be the limit of my empire.
I feel like a major limitation to a Stargate empire would be Stargate throughout.
A large enough military would need to be supplied at each Stargate to secure access. At a certain point, it is going to be difficult for the home world to supply all garrisons, even if some garrisons some self-sufficiency. Worse, if a garrison is self sufficient, how do you maintain loyalty to the home world.
