In an EOTW situation having too much would make you a target for the have nots.
This isn't the place for a zombie reference but World War Z has several stories in it which makes one realize that not everybody is going to hold hands, fart campfire songs together, and wait for rainbows while the world falls apart...wow that's cynical even for me.
I'm not one of those people who thinks the end is nigh but if something like that happens, I'm expecting a lot of people to sink to an all time low in the wake...and I don't consider myself prepared for it either. There's so many moving parts and what-ifs. I like the gear vs knowledge parallel. If things get crazy and one of those million things that can happen, does, the only thing I can trust to always be with me is knowledge...and I don't even trust that because I carry a pocket version of the SAS survival handbook ALL THE TIME.
