Actually you prep for things in the order of possibility and most preps are multipurpose.
Is it possible that your income will be either delayed or cut off? For most people the answer is yes. So you put cash aside to cover your necessary bills and you stock up on items you need to live.
These same preps also serve in case of everything from a bad storm to a bank run. From there you move forward making your plans.
” So you put cash aside to cover your necessary bills and you stock up on items you need to live.”

Yes, money could be very important, provided that it did not burn up, wash away, or get stolen from you.
I was concentrating on more serious disasters, where money might be the last of your worries.
IIRC, many in the Prepper TV series were most concerned about a total breakdown of society, as well as infrastructure.
