Mandatory government access to all communications (including saved encrypted communications) is not compatible with systems where the government or control of the government changes.
The thing that I don't really see discussed in this is the question of who do you trust to have the keys?
Personally I can't imagine entrusting decryption keys to anyone appointed by or simply hired by the Trump Administration given its history of choosing people for sensitive positions. I guarantee that there are a ton of people who think that Hillary should be locked up that would feel exactly the same way about security keys under the control of any Democratic Administration. What's more, unless the policy becomes that all communication must go to the United States government to then be retransmitted onto a final destination then security keys would be vulnerable to disclosure by anyone from a former Administration who had access to them, and it only takes a limited number of compromised or dishonest individuals to compromise the entire system.
Don't discuss whether people are comfortable with the FBI or Department of Justice or William Barr having the authority to get to all of their Communications. Discuss whether they'd be fine with Barack Obama or Hillary Clinton or Eric Holder or whoever ends up being the Democratic nominee having that access.
