I get what you are saying, but the world is not static. The concept of bookmarks and deep links thus is flawed because they do not/cannot follow changes in the world. Bookmarks need to take a snapshot of the reachable web (this is probably impossible...) or they need to expire after a few months so that the world can change.
I would hate if all nurses manuals had to accept the bookmarks of some book from 1820 just because someone once had a bookmark to the bloodletting section.
