Keith, you know what? Sometimes people are educated beyond their intelligence. I'm not stupid, and that piece I just read in wiki is complete and utter nonsense.
Economics, in general, is a load of bullshit, The bottom line is that money - fiat currency or otherwise - is a means of exchange. It is all it ever will be.
The person, institute, or organisation that creates the means of exchange does not own the means of exchange. It is a third party. How that means of exchange happens, currently, is slanted towards banks and those working in finance.
This has nothing to do with the administrators of the political system. The administrators of hte political system are just as much a user of the money created as the private sector.
MMT originated from a late 19th century economist and Hitler used this theory. This is what drove the creation of buckets of money. It does not work. Knapp postulated that money did not originate as a means of exchange to replace barter, but it was created by states in order to control people.
Clearly the man was mentally ill and suffered from some sort of paranoia.
