I would like to see a law which states that businesses cannot revoke your access to any discrete good you've purchased. Arguably, media companies wouldn't be the primary aggrieved party of a law like that; it really hurts Amazon (et al) more than anyone, being legally forced to continue serving video files you've purchased even in the face of Terms of Service breaches and such.
Which is perfect. That's exactly what we want. If Amazon has to guarantee access to content, the easiest way to fulfill that requirement is to offer downloads for customers (which I think should be a fulfillment of that requirement, and its alright if they terminate an account so long as a download was offered for all content). Of course, the Media companies Definitely don't want that, so now we have the media companies and tech companies fighting each other. Laws which disrupt the alignment of incentives between companies are the best kind of laws.
