If you have even just a bit of fame... you more than likely have a website that show all the way to contact you... so this is a non-issue.

iTunes is literally the same as streaming though.
You rent access to the content for as long as the platform wants.
DVD/Bluray are the solution to this... except not everything is released like that...
In the end, piracy wins... again... like it always has...
