The only system that can cover all five of your points right now is piracy.

1) No charge, so you're not paying for content you won't watch

2) Same as 1

3) A torrent client speaking RSS + a private torrent site that serves RSS covers this

4) You pay with nothing - no money, no data, and no viewing history

5) Files without DRM can be played on any device and cannot be retroactively deleted by the service provider

Piracy really is most often a services problem.
