'Good quality encryption results in random data, which can be decrypted to anything.'
Citationn, please. The first part is true, the second does not follow.

Easily proven. Take any plaintext data you like (images, documents etc.). XOR it with any encrypted data. Call the result the "decryption key".
Of course, it means that the decryption key will be the same size as the data, and you will need to present the encryption method as being OTP encryption, but that does not make it invalid.
