Ripping from YouTube is piracy. Again, what OP is suggesting really only works if and when you build out a large library through piracy.

Regardless of pricing you can't substitute one with the other... Spotify is a streaming service with a massive library. Self hosting means you must BYO media... and, news flash, populating a library with relevant content that rivals Spotify or would satisfy your average user will almost certainly require illegally acquiring said content.
