People want to keep the weaponization down for two reasons. The first is more or less idealism. It would sure be nice not to fuck up everyplace we go with our nation-state rivalries. The second is because orbital weapons is just a huge game changer. You put a sat with a bunch of KEMs on an orbit that just happens to pass right over Beijing or Washington, or Moscow? Cost/energy effectiveness aside, the warning time for such a strike would be tiny (far less than sub launched nukes). Does the government just go nuts everytime the sat comes over the horizon?
Yeah, not pretty.
