> Which is why we don't let private companies create currency willy-nilly anymore. As I understand, private banks extend loans, which while not being printing money, the loans being deposits (which can be withdrawn) the effect of creating currency is the same.
Yes, it's a juggling act: Person A still has $1000 on the ledger in their deposit even if the bank lends $800 of that to Person B, so if the people with deposits want to cash out all at the same time, and the bank can't pull back what they've lended out fast enough, you have big problems!
But they aren't just adding numbers to a cell in a spreadsheet without having the money to back it - a loan that can't be used to pay someone or to be turned into cash is useless. You can't just start a bank and issue yourself a thousand dollars into your own account and expect to be able to use it for anything. This would be closer to the credit card model - short term credit without taking deposits, making money on the repayment - but again, good luck issuing yourself your own credit card to buy a bunch of stuff with to "create money."
And they also aren't doing anything that couldn't be done with crypto!
