And the thing that brings on fear, the need to kill and threaten and bring into line, is the stark immutability of published work.  Try and burn it if you can in all its copies, but another will likely appear, be further copied, here or there, and spread by channels uncontrolled and uncontrollable.

Until the time when there may be no unsurveilled handing on of books, no hidden copies in the cloud, no trustworthy badge of authenticity, no guarantee of inviolate reproduction, no need perhaps to threaten the author, publisher, reader when the work itself can be so easily perversely sanitized and brought into line.
