“The topic of resale is also more complex. If you buy a movie as a physical DVD and then decide you’re finished with it, it’s perfectly legal to resell it as long as you don’t make copies. If you buy a movie as a digital download or as an item in your online library, it’s much more complicated, but resale is generally prohibited. Do you own something if you can’t resell it?”
