The mental model of web browsing and bookmarking is: "If I see it, I can get to it again." There's a partial feeling of ownership. "I've read it, so I should be able to refer back to it later." Nobody (at least, no sane regular person) reads a webpage and thinks "I have a time-limited license from the originator of this content to consume the material and only use it for their expressly condoned purposes." The vanishing content problem is like if books in your house randomly walked away just because it's the "natural state" of things to disappear.
