Why are people using the argument that if Aliens turned up at Earth now, they'd win by default as they have spaceships... Of course, because compared to them, we're rock lobbing primitives. It's like taking over a primitive planet in game, a peace of piss. It's a redundant argument and not pertinent to the point.
However, between two space faring Empires, merely pitching up in orbit shouldn't mean the same thing. Any self respecting Space empire who has spaceships with guns is going to have defences on their worlds against others who have spaceships with guns. The idea a few spaceships in orbit should be able to bend a world to it's will is, at best, a joke. A world is enormous and compared to a spaceship, has infinitely more potential to shoot back and cause hurt to anything in orbit.
And yes, they can lob asteroids from far away - but why can a space faring civilization not shoot them down? We do in an event chain already to protect primitives, rather easily as it happens.
