It doesn't matter how much value YouTube adds. It neither owns, nor does it assert that it owns, the copyright to these videos. Banks provide a value-add service for your money. They don't own your money. Value-add is not a valid legal test for copyright ownership.
The question here isn't whether youtube owns the videos, the question is whether youtube's use of anti-scraping measures constitutes DRM that, by circumventing, violates the DMCA.
Right, and again, I'm not saying Youtube has any copyright ownership here. I'm saying they provide a service which adds value and as a business they may want to protect that competitive advantage.
