I think that that alone is sufficient to justify its study—I’ll talk a bit more about why in a second. Furthermore, category theory is certainly very useful in pure mathematics—for example, the modern viewpoint of algebraic topology is that it is the study of finding functors from the category of topological spaces (or some subcategory) to an algebraic category, like the category of groups.
