I have a better example:
A $20 gold coin used to be tradable back and forth with a paper $20 bill.
Today, the $20 gold coin is worth $3,300.00.
Where did your other $3,280 go?
Inflation.
The government stole it by printing money.
And, this simple point is the one that every talking head needs to use when some crappola “news reporter” whines about how DJTrump has yet to bring prices down “like Biden did”.
People need to be told/reminded that once inflation has taken effect there is no way the price will go down unless: there is deflation, massive increase in supply (which boosts price of all other items on the market), price controls.
Money supply is dynamic.
