This is generally not true. While you can consume classics from your couch, putting together a critical edition of a book with provenance and, ideally, accompanying research and commentary takes expertise and devotion. And if you say, "I'll just read the great classics that everyone knows about," well, most of those were rediscovered or brought to prominence in the first place by a scholar who lovingly created a critical edition and made a case for why the book was important. As the humanities is gutted, increasingly there will be no one to do this work, and great pieces of literature will be lost at at a much faster clip.
Also, the idea that you can preserve anything from your armchair is laughable. If you knew the resources that go into preserving even one collection or digitizing a small set of works, you would be shocked. There have been a few people who have meaningfully preserved works outside of an institution of higher learning or a library system, but they are far outliers.
