>Imagine a future where it becomes easier to commit terrorism because of some technological advancements
Imagine a future where aliens invade, and all of our civil rights have to be suspended in order for society to be re-focused on fighting an existential war against the invaders. I suppose this sci-fi hypothetical could happen and if it did happen then the sacrifice might even be necessary. But it's not happening now, and it's entirely reasonable to classify it as both (1) unlikely, and (2) an incredibly bad outcome we should hope that we never have to face.
