You forgot one thing – once a copy of the content is server to AT LEAST one attested user agent – what prevents him from sharing his copy with unattested users?

It is easy to see that if something will make getting the content harder – it will immediately find the path of least resistance. This is the reason any new Netflix title is available for free an hour after the premiere. And the harder Netflix will try to fight this - less time will pass before their content is stolen and re-translated for free. Exactly same will happen to New York Times if they refuse to serve - someone would serve a copy instead of them – because there is now demand created for such copy.
