I haven't outlined any scenarios, but maybe you're considering a total
Internet shutdown. No such drama is needed to make the case.
Deloitte calculate the per day impact of a temporary shutdown would be
on average $23.6 million per 10 million population. Not that bad
actually. But that figure seems based on the immediate hourly
estimate from places like The Uptime Institute and LSE. Other
estimates puts it at between $11Bn per day for the whole USA [0] and
only $10Bn for the whole year [1]. In reality the impact quickly compounds,
making day 2 (24-48 hours) significant worse, and so on [2]. I am
quite sure the aggregate downtime of AWS, Azure, Google and other
cloud services in the past year has exceeded 24 hours per capita
civilian use.
Being able to take cash, as a "flywheel", makes or breaks businesses
in those times.
