I must live in some alternate reality where this just isn't a problem, or maybe the author has not described the problem well. But reading the article, it just feels like some software form of bureaucracy.
The problem appears when: 1. you have a significant number of people working on the project and 2. one of these "modules" has become too big internally where it's hard to make sense of its internal structure. Having a monorepo makes the problem even more likely. At that point, you'll probably want to start breaking up that gnarly module into pieces so that you can see its structure again, right?
