I see commercialism as exploitive, just purchasing things not so much.
Yeah, to elaborate a little, the question’s more aimed at finding activities that aren’t actively trying to rope you into buying more and more to keep up. A couple classic examples of what I had in mind to avoid would probably be like a trading card game or some tabletop game with collectible(?) miniatures (not sure what those games are called), whereas with crafting hobbies it’s simply a necessity upon exhausting craft materials.
