I'd question the assumption that all having web pages be immortal is a good thing. There is great value in letting natural processes erode items or things that don't get maintained. Throughout history, we've learned to write down and preserve important stuff. Sometimes we've gotten it wrong or we create huge single points of failure (see, e.g., Library of Alexandria), but we should be careful in assuming that preserving everything is inherently better than the historical approach.
