Exactly. If your time has no value then all is free. Most people value their time, the system does not have to be perfect. People who claim there should be no copyright because the future is inevitable probably still go to the doctor.
"Copyright not existing" and "concessions to DRM not being included in standards" are wildly different things, as are "copyright not existing" and "DRM not existing".
Ten years ago, would you tell people to go to the doctor if they asserted that the music industry could and would survive selling their music without DRM?
The music industry has been selling music without DRM since recorded music was invented. I don't think there's any surprise that they survived by continuing to sell without DRM.
9 years ago Sony was panicking, realizing what they had done, and began infecting users PCs with malware in a desperate attempt to undo the "harm" they thought the CDs lack of DRM was causing them.
And of course the movie industry was surviving without DRM for some time too. Both thought that lossy analog copying was DRM enough.
DRM model will die. But such proposals like this one with putting DRM into HTML standard will only prolong its lingering and it's another serious reason to oppose them.
