Do you buy packs regardless if your playing S4 or want its content?

There's this myth that people who don't play the game are buying packs anyway. I'm not convinced that's a thing. I have seen people who buy every pack because they treat the game as a collection, not only as a thing to do. I suppose that's legit, though -- people collect toys and don't even open the boxes! I have all of Sims 4, but I've always approached all my games as buy what I want, when I want it.
