Better for whom?  Content providers would likely consider this as
providing insufficient security for their high-value digital content
(and reasonably so, in my mind).  Keep in mind that, in your proposal,
one rogue consumer can spread infinitely many copies of the content in
unencrypted form.  This is unlikely to be acceptable to content providers.
