VPN?
Sorry, but I don't see how a VPN overcomes the requirement to associate a uh, viewing session with a viewer identification tag obtained out-of-band. I do get that it could impede traceability in the case of identification fraud, but that's not the primary concern, is it?
Anyway, if this raises awareness or promotes the practice of surfing though Tor and like, there's your silver lining. Something for the "nothing to hide, nothing to fear" crowd to chew on. So porn could lead the way on adoption of tech once again.
