e.g. Keeping some one-time use plastic grocery bags around for temporary tote bags or for bundling up trash is fine. But keeping 2 dozen when 1 dozen is a year’s supply for your household is just silly. And keeping every one you get every week “just in case” is outright wacky.
It’s the inability to distinguish between “enough”, “too many”, and “stupid too many” that’s disturbing. To me. Some folks’ MMV.
