Well if decryption is so justified then brute force breaking that takes significant resources so it's hard to unnoticeably misuse would be a good approach. When you can only break into 100 phones a year, then there's no slippery slope or fascist governments that could wildly misuse it for their own gain because it's not physically viable.

Ok! That is a sensible rejoinder. Make a proof-of-work system that limits the authority from making more than n requests in a space of time. A good brake on abuse.
