I get your point, but as a counterpoint consider this: my mother's cousin recently scanned a picture of my grandmother and her brothers (one of whom was the cousin's father) as babies, along with many other old family photos. I posted the scans on Facebook, so now everyone in the extended family (dozens of nieces, nephews, cousins, what have you) can see them. The pic of my grandmother is around 85 years old. Is the original photo a precious object, worthy of cherishing? Certainly (and obviously, given that it's survived all this time). But, you know, it was her precious object alone. Now all of us can see the picture any time we want. This is GOOD.
Is a first edition of Robinson Crusoe a precious object? Of course. It's also (I'm guessing) quite rare and extremely expensive. Yet anyone with a Kindle or Nook (or even a computer) can get Robinson Crusoe from Project Gutenberg for free. Most of the PG audience isn't going to be able to afford a library full of fine leather-bound books. The choice isn't between the fine leather-bound book and the etext. It's between the etext and not being able to read the book at all.
We've seen this play out in many other areas. Mass-produced clothing is another example -- is it as nice as individually-tailored clothing? Nope. But most of us can't afford a wardrobe full of custom-tailored stuff (and historically, people didn't; most folks had a set of "work clothes" and maybe one set of "Sunday clothes", if that).
For that matter, exactly the same scenario played out when the printing press was introduced. Esthetes decried the loss of the hand-written medieval volumes, lovingly calligraphed and illuminated by highly skilled scribe/artists. They were breathtakingly beautiful. One book also cost somewhere around a year's wages for a skilled worker.
