There is no need for double entry accounting trickery nor loans to create money. All bank needs to do is to say that they owe me money and they have created money at that very moment.[1] Simple as that. And they do create money without lending all the time! It is nothing special. When a bank "pays interest" to your account, do you think there exist some new loan that is needed for that money to exist? Nope. Bank just decides that now it is time to add some more money to your account. That's it. Or when bank pays salaries to the personnel or dividends to the shareholders? Nope. No lending associated whatsoever. Just money added to their bank accounts. (for simplicity's sake, I assume that the stakeholders have their bank accounts in the same bank)
[1] Which to me implies that there is not that much interesting happening at that point. I mean, a bank could enter a few centillion dollars to my account, and technically the money would be created. But in practice that is laughable. Nobody in their right mind would imagine a second that the bank would be solvent and actually be able to pay me the money, so in reality that money does not exists (no credit...). So even if the traditional model of banks lending deposits forward is technically even more wrong than the banks create money from double entry accounting trickery, in reality that describes much better what actually economically is happening in the financial industry. But that is just my opinion...
