GAS never concerns cheap things like key rings
But that's logical. Key rings are a dime a dozen. They can be had anywhere. You only need one or two and the decision to get one takes no effort. It's the perniciousness of GAS that there's always something out there that you can use. Or rationalize to use. And that it is often on your mind. When you think you need a piece of gear, you start thinking of it a lot. And the more you think about something, the easier it becomes to rationalize a decision to get more. In contrast, when was the last time you thought about getting a key ring? Probably only when your old one became unusable.
Although I am quite sure that there is someone out there who has a key ring fetish, a seriously obscene collection of key rings and who is always on the lookout for new ones. Rule 34 does not just apply to p0rn.
