The utility of breaking old classically encrypted messages isn't really an existential problem for anyone, and there are no lost great secrets buried in encrypted intercepts that yield disruptive power if they are discovered today or anything like that. Think of it as a control plane vs. data plane, where you have the state as a control plane, and if data can escape its purview, or worse the data plane can generate control messages that subvert it - you get existential uncertainty and risk. It will never let itself be reduced to a dumb pipe. Encryption represents a limit on the absolute sovereignty of that control plane, so the resources to contain it are a constant need.
