In a banking system all money comes from debt. So when new money, dollars for e.g., are created, in the same time, some individual, company, or organization became legally obligated to pay these dollars back.
Producing the debt does not necessarily mean producing the real value.
Producing the debt is as easy as "producing" a you-name-it-coin.
And no, I personally did not sign any obligation to pay any produced-by-bank debt. Especially, the dollars' debt.
Nevertheless, "a banking system" is a Ponzi scheme as well: they (banking institutions) pay interests/dividends etc., but they do not produce themselves any commodity (yes, say hello to Mr K.Marx).
