Let's say a video maker did create a Facebook page, and loaded all their videos onto it. That does not solve the problem, because Facebook is not an open, search-based system the way YouTube is. Facebook users will only see it in their NewsFeed if it is posted by a page they are following, or engaged with by a friend.
YouTube has a system to recognize copies of known videos, so they can prioritize the original video when they serve search results, or recommended videos. This allows them to soak up the demand for a particular video, and direct it at the appropriate copy (the one uploaded by the video's creator).
Until Facebook has a similar system, multiple copies of a single video can exist within Facebook and potentially never cross paths, since propagation depends on the local shape of the social graph, and how EdgeRank moves content through it.
That means that even if a video creator uploads their own video to Facebook, they can't soak up all the demand for it.
As the guy in the article says, the only way for him to become aware of a copy is if it lands in the NewsFeed of one of his fans. Whereas on YouTube, anyone can search for any title, and Content ID also finds matches.
