The critical flaw in this is the "delete" button. The user can dang well delete a pirated book if (s)he wants to. Having "delete" as a default will mean the book will be deleted accidentally before the copyright runs out.
The real goal here is to throw our society into another dark age by making it impossible to preserve information.
Take a look at the political coverage on the web. McBama and O'Cain are both using DRM from adobe to keep us from saving any videos of their speeches, so they can lie and claim anything later. They only reason to do that is to make it possible for them to cover up their lies by airbrushing history at a later date.
I can not imagine someone who is that evil, but our whole society seems to not mind.
Andy Out!
