Yeah, we all know what fractional reserve banking is. But a debt exists at the same time and the idea is the money that was lent builds something, creating value. Let me borrow some gold so I can use my herbalism expertise to make some potions and sell them for a price that is greater than the sum of ingredients. That's how value is created. Saying loaning money inflates money de facto is disingenuous. Wealth is being created on the other side via goods and services.
