You still need to add to that the cost of the films/series themselves. (You can choose not to and sail the seas instead, of course, but then it's no longer an equivalent exchange).

Well, yes, but we've already established that entertainment is an ongoing expense. You just have to decide to spend that outgo in a different manner than giving it to the streamers. You start with a storage pool and way to play its contents back, and then you start to populate that storage pool. I have not once suggested getting entertainment for free. I have only suggested there are other ways of being entertained than by the streamers with a large portion of the same content.
