I would like to hear an explanation for how interest can work in conjunction with an inflexible money supply.
Will mine do?
Put simply, Moneylenders do not just hoard all the money that they get back. Yes, it's entirely possible for someone to borrow
BTC20MM and end up owing
BTC36MM. This does not mean that they will be unable to pay it, necessarily, just that there will have to be at least
BTC15MM that goes through his hands (and back to the moneylender) twice. While he's paying his tremendous debt, the economy is chugging right along, and he's providing value to that economy in order to get the
BTC that he owes.
