It's pro national security, not pro state security. It's important to make the distinction, think of guns and the second amendment to the US constitution. Very much secures the territory, population, national culture etc, but weakens state control. Why?
It's because the state does not operate representative of any group. No state can do that. It simply has one special population from which it derives it's resources, and then a bunch of other populations and actors, and it has to contend with those two sets differently. It has to operate as if you are a potential enemy. Often, this means managing you like you are already an enemy. It treats the other set similarly, except it has to manage it differently. To a state, you aren't the special thing it exists to protect, you are a caveat with how it contends with all entities that are potential enemies. It has to protect you to ensure it's continued survival, but that's not all it takes, you may threaten it's survival, and in that case, you are it's enemy.
