Suppose I was selling gum and I was asking for 10 pennies for a piece of gum. So I say "In pennies, the price is 10". Someone could say "But in nickels the price would be 2, and nickels are as valid a unit as pennies." So I would say "OK give me 2 nickels". He could say "But you can't say the price is 2, because in dimes the price is one. You see the gum does not have an actual price being that the price is different in different systems of coins. It would have to have the same price in any system of coins in order for the price to have meaning." I would then kick him out of my store.
