That’s assuming the key and message are entirely independent. If you or the recipient isthe type of person or doing the types of things that would attract surveillance from a nation state (because realistically that’s the one of the only scenarios where non-esoteric privacy practices might not cut it), it’s not unrealistic that they’d intercept both your digital and physical mail and would be able to correlate them.
