I think the difference though is that toothbrushes and oil filters are necessary, but nonstick pans are not necessary. They are temporarily easier to cook with and to clean, but then they wear out and need to be replaced. I moved into a more BIFL stage of my consumerism a few years ago, and I have chosen not to replace my nonstick cookware as it wears out. And as it turns out I can cook all the things I used to use nonstick for – eggs, fish, potstickers, pancakes, etc. – just as easily in cast iron and carbon steel. Plus, since it is the coating that wears out and not the pan, even an expensive All-Clad nonstick lasts the same amount of time as a super cheap T-Fal (I speak from experience).
My only major gripe with your list is the inclusion of nonstick pans, which have a very limited lifespan and generally considered disposable (and non-recyclable). You have multiple cast iron pans on the list, and you could also add carbon steel pans (very similar to cast iron), which are effectively nonstick and definitely BIFL.
