The risk of the payment system getting shut down and people being unable to make payments for a while is real. And it is one good reason to be less reliant on digital payments.
But there is also the risk of bad actors, which could also be e.g. Russia, getting access to decades of payment history through a hack, if everything is digital. Having that data for every citizen of a country could enable efficient profiling of people in the country using big data analysis technologies.
The kind of thing you could find out with the transaction data is who are working in the military or security police, who is sympathetic to Russia and at the same time vulnerable to work with foreign governments, and potential blackmailing material relating to people in these or other groups. I'm sure the analysts working for the bad actor can come up with even more useful things to look for in the data.
There are of course a lot of other data sources that bad actors are interested in and that are easier to hack, but the financial history seems more comprehensive source of information than most other ones.
Or entities. The USA had a brief oil crisis recently because one of the major pipeline companies had their billing system hacked. Since the company couldn't verify whether someone had paid, they just didn't supply any oil.
Couple that with some misleading news stories and social media panic, and it blew up into a proper shortage from people hoarding all the petrol, and leaving none left.
Do you have any more info about this?
Here's an article about them turning it off because of being unable to verify the bill: https://edition.cnn.com/2021/05/12/politics/colonial-pipeline-ransomware-payment/index.html
And here's two attributing the issue, at least in part, to panic buying: https://www.aljazeera.com/economy/2021/5/11/petrol-shortages-sweep-us-as-colonial-pipeline-remains-down

It already happened in Ukraine during the NotPetya attack by Russia in 2017

You don't need an external actor for that, a government can very well do that to their citizens...
Exactly.
Part of the card processing system goes down often enough due to various technical failures that it should just be good business sense to always be capable of accepting cash.
Yup, I keep a fair amount of cash on hand at home in case there's some kind of mass outage so I can at least get essentials to last until power is restored. Oh, and I also use it for my kids' allowance and for baby sitters, but I have larger denominations as well in case of emergencies.
That said, I have been considering using cash more often because I really don't like all the tracking that already goes on, and I certainly don't want the government having that data as well. But cash is super inconvenient because of small change, so I haven't made the switch yet. If we could get rid of the small change and just round prices a bit, I would seriously consider going back to cash.
Just a note, high denominations are not great during emergencies, unless you mean big purchase emergencies. Buying food and gas with high denomination bills may end up in seller not accepting the bill because they have no change. Or happily accepting that bill despite having no change.
For small change, you could take the jar to your bank and make a cash deposit (and see the cashier die inside). In some branches they have machines for counting change.
Yup, exactly that. I'm in the US and keep a few hundred in $100 bills, with the rest being smaller denominations. I usually have about $1k in cash in a safe, with lots of small bills. So that should be plenty to handle a couple weeks worth of groceries, or a couple large purchases (e.g. paying someone cash to move a tree or something).
Couldn't they run a Chaumian digital cash server? It's got top notch privacy, with the only downside of being a trusted central authority... which fiat currencies need anyways.
