You don't get access to the file itself, it's only viewable inside the Youtube app. It's DRM'd content, subject to Youtube's corporate decision making (they might revoke access and wipe the video at any time), or put arbitrary limits on it that wouldn't be there if you had the actual file itself. Basically the content producer (like a music label) lends Youtube their content, and then Youtube lends it to you.
