Sure, no human has ever read 70 petabytes worth of books. An archive is not the same as a local public library. The latter holds a small collection of mostly frequently accessed items (e.g. the published works of Dickens, Austen, etc.). The former holds a much larger collection of rarely accessed items (e.g. every letter written by/to Dickens that survived, every political pamphlet published in Philadelphia in the nineteenth century , etc.). If your point is that most items in the archive will be rarely accessed, I don't think anyone will disagree with you, but suggesting that the literature of the nineteenth century is no longer of any interest was perhaps not the best way of making that point.
