@Jim,
I am thinking after only 2 weeks and the grid and computers came back, I think things would resume as they did prior to the event, in the bill paying regard.
6 months or longer . . . I dunno. Assuming the collapse of the JIT/BAU centralized food system we have, the economy, government and someone claims they are from the bank and you owe them, you might be able to hand them a bag of turnips and declare your property is paid in full.
I have seen people post of how they will use PMs to pay for their taxes (why they always bring up taxes, I do not know) so they will not be in debt to the government.
IF there is a collapse, and we are only 9 meals away from chaos and anarchy, and if the estimates are correct and 90% of the population will be dead in the first year, what government are you going to use your PMs to pay your taxes?
Just like what if during the collapse your house burns down. 2 years later do you get to make the claim to your insurance agency? There is no one to call, no adjuster, no investigator at the time of the fire.
Are those computers that held that information still workable? The people who knew the passwords still around? Are there people around who have the knowledge to get into the computer to get those files? What about the hard copies? Are they in a air tight safe (please note, I read an article about a guy in CA with a gun safe, the wildfire was so intense, the guns inside were ruined)? Or have they been used as toilet paper, fire lighting material, or ruined due to the elements?
I agree with John Park, great post!
@john Park, not sure if I have the power to move the OP to the Finance section. Will research and get back to ya.
