The music industry survives without DRM.
When books are less expensive, and easy to use on any ereader, piracy will end. And we may even grow new readers.
Books now must compete against all sorts of entertainment that did not exist a few decades ago. Consider that you can buy movies for the same price, or less than many ebooks--and that is a problem. Book publishers, traditional publishers, are in serious trouble. But at the other end of the spectrum, readers who have bought into ebooks may find the new book gate-keepers are as bad as the old. The saving grace is that Amazon still allows authors to remove DRM when they publish, and Amazon allows new authors/publishers to basically set their own prices. If Amazon continues to allow DRM to be optional, and does not use the sword they wield, things may not be grim, but already Amazon must be seeing the benefit of lock-in to Kindle readers.
