It's also pretty easy to launch another one into orbit to replace it? I'm not sure I understand what you mean. We can have all these options simultaneously. The easiest targets are where the faster paced more offensive action is going to be.
People have been talking about waging war in space for many decades now. All the arguments for and against it were made a very long time ago, and it was decided it's a hell of a lot better that way. Even a nuclear blast in orbit is more tolerable.
Space superiority is just too damn appealing as the next frontier after land, air, and sea where we've been stuck in stalemate for a while. It's perfectly natural we go to space for this, including the datacenters.
