Need good name for fdr/paper money/paper

At the risk of being cynical, I would have to call it scrip.

And as much as I do not like quoting Wikipedia as a source, it was the best I had at the time of this reply.

No, the Friedman would be fiat money.

do you have sources for this claim?

You said it is a claim for nothing.

im asking for a source to your strict equivalence between fiat money and nothingness

Fiat money is paper that has ‘value’ because of government fiat. So the Friedman would not be fiat money - unless Mr. Friedman is a monarch who forces his subjects to use his notes.

I would call them Happy Points. Useless pieces of paper, but somehow it makes people happy when they get them.
