> Its a bit odd that legally one can rent out physical disks, but there is no corresponding way to legally get permission to rent out streaming content without negotiating with the rightsholder. But thats how it is...
It's hard to think of a good fair regime to do this under.
At least with a physical disk, there's a maximum reasonable rate that you can turn the disk around between users and you need to have enough copies for whatever the lifecycle peak demand is.
We do have an audio compulsory licensing system for things that are purely songs. But with video works, there's not a clear boundary for "how big" the work is-- how do you treat 30 hour anime series vs a 5 minute Pixar short? How do you treat continuing medical education videos vs. fluff amateur made content? Etc.
