I disagree. Sources are not solely there so that you "prove" what is presented is factual(although it is nice to see where the information comes from), they are there so that someone can use your video as an entrypoint to read about the subject itself more throughly. They aren't obligatory of course but it would be way better if they were a standart for this type of video essay.
In the video in question he states in the intro that he's going over the subject in brief and has links to other videos that more thoroughly detail the subjects. I do agree with you that sources are nice, and pointing people in the right direction for their own edification is important.
