But aren't you confusing the means of exchange with the creation of value.

The creation of value is me taking energy from the sun and converting that into a chair.

You lending me money is you extracting value from artificially being a middleman.

It would have been more efficient to write an IOU to the tool maker, make the chair and pay back the tool maker directly.

Now sure that IOU isn't that fungible - however that highlights one of the absurdities ( if I understand it correctly ) of the current banking system where private banks are able to in effect issue IOU's on their own basis but put mine and your name on it as a guarantor - resulting in the public having to bail out banks when they over extend.
