I don’t see how this is complicated, it’s simply a technique. The creator of the video has no stated agenda, and it’s on the viewer to decide whether or not they want to learn and apply this method. Lots of people find joy in solving the little things in life that would otherwise cause them frustration. One of the top comments on the video is a nurse saying they’d been tying their scrubs with bunny ears for 30 years and always had to keep adjusting them. Certainly it isn’t overly complicated for them.
