I think we sort of agree. The paper is a paper. It's in "theory space". In practice things are different and the paper might have some implications in edge cases. Also in practice people test encoders etc. I can see how it can be misused by the other crowd. I wasn't trying to say that lossy encoding is no good. I can't tell the difference between a mp3 and a flac if the bitrate isn't too low. But I know I don't like low bit rate mp3. I wil read the other comments.
