It’s how all of it works. Money is just balances on double-entry bookkeeping, and the paper currency essentially is a piece of paper that the bearer of that paper is good for moving the balances in that ledger system.
By that logic any bank could grow arbitrarily large by just underwriting more loans. Then there’d be no competition between any of them and my job would be so much easier.
Yes, the limit to commercial bank lending is creditworthiness and default risk (because the bank is left holding the bag when a borrower doesn’t repay), and the cost of maintaining liquidity (the bank can borrow against the loans it owns, but it may cost a higher interest rate than they’d earn on the cash they’ve lent out). This paper lays it out pretty clearly, and is basically the near unanimous view among macroeconomists.
Or, in some regulatory environments, banks are required to maintain a minimum fractional reserve, which limits the total amount of loans it can lend out with its underlying assets.
But the money is created when the loans are created, and destroyed when the loans are repaid. The other stuff behind the scenes to give the system stability is important, but doesn’t actually create or destroy money.

And almost all of those ledgers are now digital.
