There needs to be an healthy balance of preparedness: knowledge/training, community/friends, equipment, mental, physical and financially.

Having lots of stuff is not much help, if your house and car gets repossessed. I read about people who spend lots of money on things in case 'shtf', but are unable to cope with missing a pay check. Getting kicked out of the house is something that seems more likely to me.

Besides I checked the evaluation of large scale evacuations in my country. Most people skip government shelters and just book a vacation or stay with friend/family. Having money to travel and pay for your stay can be the easiest and most comfortable option in an emergency. besides having a good emergency fund makes life a lot more stress free. Be able to get fired, have mayor expenses and not financially care too much about is just great in keeping yourself stress free.
