Generally it's good manners when asking people to take the time to watch a video, to be clear and specific about the contents of the video, how it supports your case, and why you are asking them to sit through a video instead of writing the points made yourself and allowing others to digest them more easily.
This is especially true when you enter an argument by making and defending something silly like an appeal to tradition.
Your argument with the video seems to be an appeal to authority and a shrugging off of the burden of proof, asking us to prove why Rickards is wrong.
You can point to Ronald Reagan, one time leader of the free world who happened to be a Christian and consult astrologers. In a discussion of the validity of Christianity or astrology, linking to a video of Reagan and asking us if we thought he was delusional would be the same kind of red herring appeal.
Either the facts stand up, or they don't. If you want to make a case that certain informed authorities support your view and their opinion should be taken seriously, then make that point. Don't half-assedly suggest it with a link and a JAQ.
