People are using less cash, not more and more electronic money, not less. And why would there be bank holidays?
There was already one issue failure, last November, which unnerved the cc companies.
I hadn't heard that. Who had an issue fail?
A few failures in a row would force them to cancel millions of cards.
How would that make my electronic money worthless?
so they could only do electronic transfers.
Yeah, electronic money.
Very few businesses have automatic check withdrawl
What's that?
that along with overdrafts
Customer overdrafts?
would quickly force them to abandon credit cards and checks
I think they'd be more likely to accept credit cards (debit cards too, electronic money again).
But because there is such a profound physical cash shortage in the US right now
It sounds like you imagine a time in the recent past when physical cash was above some magical % of all money when all was well. What was the magic % and what year was the last when there was no such "shortage"?
The credit card bond failure was in November, 2008.

As far as the rest of your questions, they almost look automatically generated. Not my problem.
