Read my original comment again. I explicitly talk about banks borrowing to maintain liquidity. It's an important limit on their ability to create money, and nobody said anything about infinite money supply.
But it doesn't change the fact that the act of money creation is caused by a bank creating a loan, and the money comes into being without a single physical act of manufacturing: it happens on a computer, and before computers it happened on paper.
So without claiming that money was unlimited, I did point out that money itself is overwhelningly digital in the modern age. And the limits don't come from any physical constraints.
