I doubt event the author incorporates all 100+ models in their every day life, but I don't believe that is the point.
These models provide some kind of an insight into some of the underlying concepts of different domains. Some of models are generic enough to have a very wide range of applications (ex: Hanlon's razor). While others are a bit too specific (ex: Fat-Tailed Processes).
The common thread across all models is that once you understand them, you have an access to a new vocabulary which can be used in almost any domain (ex: The military mental model of Asymmetric Warfare in the domain of business. In general, if you are a business person I suspect you are going to find almost all of Military/War mental models extremely useful).
The important point is to understand this metaphorical method of thinking, of how different things can be connected through abstractions, and then generate insights based on that. Once you start doing that, you'll accumulate a lot of different mental models without even realizing it. Almost everyone already uses mental models. Doing it consciously makes you that much better at it. :)
I haven't gone through the referenced paper but I think it should answer your question to an extent. Also, I feel that the author has been quite diligent has linked to multiple papers to back up his points.
