ItsJustMe, I have not bought a multi tool yet because I do keep thinking what I would actually do with one. Like you said, what could really go wrong with a bike besides a flat tire?

I rode my last bike for nearly 25 years, through college years and lots of recreational riding, and never had one issue with a breakdown on the road. I never even got a flat tire that stranded me (only the slow leakers that showed up as a flat tire the next morning).

Maybe I shouldn't even bother with a multi tool?
