This seems to be starting with the assumption that it's possible to prevent people from downloading the videos. That is a false assumption. You can, after all, just play the video and record it. Even if the entire machine playing the content is flawlessly locked down, you can just record the output.
The efforts at DRM done by companies like Netflix is done because the companies that licensed the content demand it. That doesn't mean the DRM works. You can find torrents of all those shows.
