So copyright demands the destruction of creative works... But creative works only exist because of ex-post-facto extensions to copyright after they were created, and if we do not hurry up an place Shakespeare's works under copyright for the profit of Sony, they will no ponger exist because Shakespeare has no motivation to write them. All this is especially true outside "Science the the Useful Arts," which is where corporate profits are most Constitutionally protected in the USA. \s
