I found the 'requirement' of set theory in the book is very 'common sense' and doesnt really use any advanced knowledge. It depends greatly on finite sets, which is easily and intuitively drawable. The point of these instructional methods is to build an 'intuitive sense' or "system 1" knowledge of category theory. Having a lot of easy to grasp examples to help you start forming the theory in your head i find quite valuable.
