"It all worked great for a while, until one day they found they had too few pieces of scrip. Every couple had only a couple hours left and, having so little, they didn’t want to waste it."
Some are lost (you need to print money to replace torn/lost bills).
Some people join the group without new scrip being added (money supply needs to grow with population).
Some people de-facto left the group (kids grew up/they moved away) while holding scrip (people stuffed cash into their mattresses and forgot about it/died).

Wait... where did the old pieces of scrip go?
Mr. and Mrs. Jones from down the street were saving them all in the hopes of getting rid of the kids for good?
He's getting the story a bit wrong. One or two of the couples will have a whole lot more scrip than the others that they've saved up.
