Somebody's gonna find a way to militarize space. Why would we wait for it not to be us? Do you not realize what a hostile nation could do with military spacecraft holding satellites hostage? Banking, TV, internet, phones, literally everything needed to grind any nation to a halt. Tech is getting to where it's a plausible concern, absolutely no reason not to be the first. Not to mention someday we might be able to hear EVA on the EBS, "ION cannon ready".
