The way I'd read it was that any money in bank accounts, loans etc. had three zeros slashed off them. Any money "held" electronically if you will.
Under my bed my £100k would still be there piled up as my £100k. However if it had been a number on a screen which is, to me, what happens when you store it almost electronically and not there in *your* hands, in this case I'd have be able to draw out £100. That was my interpretation of it. Worrying as I never realised a country could actually do that if they so wished.
This regarding debt as a number instead of money that has passed through your hands is many people's downfall. You can get a credit card with £5k limit and use all of it and get shiny things but never see a £.
So, people, like my sister for eg. don't even see it as money that they are responsible for, and a result don't really register with paying it back or borrowing too much. It's just a number on a statement, it was almost never like it was money.
My sister refers to any loan, credit card etc. "when I get
my money..."

it's not yours.
