I've bought 1,000s of paper books and they have all gone away. Some were burnt up in a fire, some were lost and most I gave away as they were too cumbersome to move etc.
Life went on. I'd be more upset if I couldn't get new ebooks. Could happen, someone could actually build a holodeck where we would live the books
Still if you have an large investment in ebooks, maybe you could get insurance.
