The point of this series is to address the subset of his readers/commenters/his followers on twitter who have various flavors of delusions of the past being some utopia of multi-generational housing/family units and that wasn't just the reflection of harsh economic realities. He's already written blogs addressing the extreme on the other end where people assume too much economic freedom and upward mobility like is typical in video games. He's done other blog series in the past that are more specific about specific things. His best work is on ancient military tactics and strategy. Every now and then he does these "baseline knowledge/understanding" series when he gets fed up with a particular group of idiots in his comments. It's like a teacher getting a class and being like "oh, you really are this dumb, I guess I gotta teach prerequisites before we dive in" even if they're not the best person to teach those prerequisites.
