Let me rephrase something for people to REALLY understand this statement...

Banks are extremely profitable because they are able to perform an instant arbitrage on the money that are deposited with them. In a certain sense, they are making money out of thin air. No wonder there is a saying,

BANKS can issue dept... by asking it to central banks!

This is basically the same role of a "SHIT COIN" creating crypto... and then saying... its worth money! The difference thought... is that shit coins... DIE!...

BUT BANKS DON'T!
