The solution is simple: YouTube will become a media licensing marketplace! That way it knows for certain if you've broken the rules.
Plus, it's a nice little side biz, to have de facto monopoly marketplace, enforced by the fear of BS infringement claims like these. It's a monopoly that's very hard to attack in court, because hey you're free to license content anyway you like! Litigation will take decades, and the customers can't afford litigation anyway, so let's do it!
I had this exact thought. It's obviously impossible for youtube to verify music was licensed since that licensing happens off platform. Clearly the next step is for them to vertically integrate and handle the licensing themselves.
