Terry Pratchett's Making Fiat Money?

Okay, so Terry Pratchett's latest novel is about the central bank of Ankh-Morpork issuing fiat paper money, instead of relying upon gold, and all this has been put in place by the Machiavellian Vetinari, under the auspices of...wait for it...Moist von Lipwig?

Gold...central bank...Moist von Lipwig...fiat currency...Ludwig von Mises...central bank...gold...errrr.... shurely there's shome mishtake?

I must read this monkey and figure out what the heck's going on.

It's long been my suspicion that Mr Pratchett has been on a long road from Guardianista to Pseudo-Austrian (and good luck to him if he has been), but this is getting very close to the bone, even for him. I will be back on this, even if I have to shell out on the hardback. I mean, Moist von Lipwig? You've got to be kidding me.
