My main thought behind this is that you shouldn't have to worry about sieging individual worlds in a solar system.
So you don't have to siege one tiny moon colony at a time in a solar system with 20 moon colonies. Instead you siege the whole solar system and then capture/destroy everything once the siege is complete.
