Can somebody explain to me how backdooring every app does not lead to the real risk of an entire population's bank accounts being emptied, or similar more hidden but widespread attacks that absolutely cripple any country doing this? Almost immediately, enemy State actors will have almost as complete access as the government passing the law; blackmail will become trivial; they could just subtly weaken adversaries nonstop over the years for a more patient return, etc? It just seems ridiculously dangerous. How is having a single point of failure (or handful of points of failure) for an entire country or continent defensible simply from the perspective of opsec?
