I don’t think “hobbies” is the same kind of thing. One of the ideas that comes along with the idea of paradigmatic structure is that of inheritance, which you may know from object-oriented programming languages. So, “animal” has certain characteristics that are true for all animals. “Beast” inherits those characteristics plus those that are characteristic of beasts, but not birds or fish or insects. Likewise, “insect” inherits the general characteristics of animals, plus those true of insects, but not of beats, fish, and birds, and so on. Similarly, “cattle” inherits from “beast,” “robin” from “bird,” and so on. I don’t think “hobby” works like that. A wide variety of activities can serve as hobbies, but not necessarily so. Making ceramic pots is a hobby for one person, but an occupation for another. Card tricks are work activities for a magician, but a hobby for someone else. And so on.
