It is a great essay until this paragraph::
The key to the opt-out mechanism I propose is the selection of a single digital file format or family of formats capable of conveying copyright management information as defined in section 1202 of the copyright act. The format will probably incorporate digital rights management capability because the people who will be using it will desire that feature, but there's no need for any copy-protection to be hack-proof, or even exceptionally durable. It should also be compatible with the current generation of digital playback devices, including CD players. I'll call the format *.drm for short.
This aspiration: "It should also be compatible with the current generation of digital playback devices, including CD players." is impossible. CD players play unencrypted, uncompressed digital audio. A drm'd format would require new players.
