All right, I've sacrificed myself for you guys and watched the video.
While it takes a minute or so to get to "Nothing," the intro says that it's about all the things you're doing wrong. Then it covers basically all the bad house rules people use (including some I'd never heard of, and wondered what people were thinking), tells you the real rules, etc. It does discuss the reasoning behind not using house rules--every single one of them prolongs the game or increases the chance of fist-fights. And of course using the real rules to your advantage can really increase your win chances.
Also, fun line (paraphrasing): "You can sit in jail, and if you're rich enough, you can just continue to do business as usual, much like in real life."
It doesn't help that many of these videos aren't edited or scripted, so it's just someone saying um and ah a lot punctuated with uncomfortable pauses.
This one was definitely scripted. I think
most of what I watch on YT is scripted--certainly the best informative Tubers out there are working form scripts. The only one I watch who doesn't is Brady Haran, and in general, because he's talking with actual mathematicians and scientists, they actually get to the point (although Cliff Stoll, for instance, rambles some).
