It doesn't do you any good to take an area and it have be an irradiated wasteland. They have planet killing weapons, why fight at all? Cause lives are cheap in the Imperium, habitable worlds are rare enough to be worth dying for, space craft can't occupy land, and space craft are rare enough and expensive enough that you have to make a concerted effort to take out anti ship weapons with boots on the ground.
