Did you read the article? The author builds a very interesting mental model for reasoning about what purpose each provides. Basically, as you are alluding to, the choice between Monoliths and Microservices is a false dichotomy. By analyzing _why_ we feel we must choose between them and the benefits they each provide, the author providers the reader with a framework to understand how/when to make choices about software isolation. He approaches it from the perspective of Security, which tends to align well with overall "system complexity". It was a very good read and I'd encourage you to grind through it all (and not skim ;) ).
