Yeah it’s kind of the entire point I was making. If I could only listen to the music on YouTube that’s been properly licensed and identified, then I wouldn’t use YouTube for music. In that situation it would just be another Spotify.
Here’s an example of something that’s absolutely not supposed to be on youtube, which the IP owner goes to great lengths to enforce. But people keep reuploading every time it’s taken down. It’s literally a bootleg.
