the problem with backdoored encryption isn't making a cypher with multiple decryption keys. It's keeping secret that's worth billions of dollars and shared among 10s of thousands of people. The difference between backdoored encryption and no encryption is whether the backdoor is known to the public.

There is a coherent set of values that lead to saying "no encryption", but not one for "only backdoored encryption".
