This reminds me of the "articles" I see that say why people are getting out of cash. When I see them, I think who the hell has cash?
I have $18 cash in my wallet. Well prepared for civil war!

PS. I'm guessing my house and the electronic records of my mutual funds will both survive whatever civil war occurs, should we enter a non-Schuant timeline. But you never know. Anyway, my goal in that event would just be to find out what happens...because by then I'd have survived, probably after helping some neighbors survive as well.
Fwiw, I think that if you are prepared for Standard Disasters (fires, floods, hurricanes, etc) and FIRE, you are already prepared for Civil War. Your emergency plan probably includes enough cash, food, water on hand to get through a couple of weeks with your city's supply lines cut/downed, or at least a few days. You have friends among your neighbors, some variety of DIY Mustache skills, the ability to plan, and the ability to be resilent. You have some diversification among your assets; a civil war might destroy some of them, but probably will raise the value of others. You will survive.
