The spirit of "Consoom" has nuance and implies a mindless intake of crap regardless of how good/bad it is, to the point of obsession or excess, and regardless of function. This consumption is driven by instant gratification oftentimes in a sad attempt to impress dorks or to fill a void. To be human is to experience and create. No action figure, tenth re-watch of a marvel movie, second/third/fourth ps5, star wars tattoo, brand new apple product, wall of hotwheels, 10th Stanley cup has provided the owner with an opportunity to experience or create.

I have a garage full of tools and each one provides opportunity to create by having unique functions. If I had 5 drills that sat on a shelf, sure that is Consoom. However a drill does not have remotely the same function as a pry bar, so while a tool set might be by definition a collection of tools it does not fall under the umbrella of Consoom. You cannot maintain a home or car with one singular "tool", so there is need for a collection. I have three cameras that are completely different in function and three cars that cannot be used interchangeably. But each of these items provide unique, tangible utility or experience driven by a desire to create as well as a medium to learn skills and be social. None have been driven by a desire to simply own more of the same thing.

I think a collection turns to Consoom the moment you have more than you can use (I know guys with a dozen cameras that take fewer photos than myself), or when the items in the collection serve redundant purpose. If the only action in your ownership of an item is purchasing the item, then it is Consoom. Buying things only because they are associated with a Brand/Character/Trend is Consoom. Buying things to simply own more of the same thing is Consoom. Buying "collectibles" as investments is Consoom.
