Essentially with respect to the banking system, economics has built on a false understanding of how it works (fundamentally the incorrect claim that banks lend out their depositors funds), and never gone back to fix that with a correct understanding. So we have the situation that the Bank of England published a memo reiterating how that deposit money is created through lending about 8 years ago now, but there are still papers being published with the incorrect understanding as a basis.
And now we have the Bank of England essentially proposing to "solve" that problem by introducing a digital form of asset cash. It will be very interesting to see what goes on the other side of the balance sheet for that.
