The first thing I thought of is all the violence I've read about on Black Friday, the day after Thanksgiving in the US. People line up outside big box retailers, and there have been people trampled in the ensuing rushes. People die everywhere for all sorts of reasons, and 91 or even 300+ is not a large number--tragic, yes, but it's not like a massacre (and I'd still like to hear how they died).
I've always been a fan of keeping some cash at home, locked up in a safe. I think that's always a good idea, whether you're anticipating a financial collapse or not. You never know when you're going to lose your debit & credit cards or when local businesses suddenly lose the ability to take electronic payments. That happened in my neighborhood back in 2011 when we got hit by an early blizzard and the whole town was in the dark for about 4 days. It was a nightmare, but I was able to buy some food at the local Walgreens because I had cash.
If you live in an economically unstable country, I think keeping fiat on hand is a must. If you can afford it, that is. It's not always easy to put money aside.
