Does money grow on trees?

My daughter drawn on a paper and wrote this:

Money=Paper=Tree

She said that money is made from paper and paper is made from tree...

I told her, maybe... if you plant fruit trees and have fruits, you can sell them. Maybe you have some rare plants that other people may need, you can give them for a small token. Maybe you have a good rootstock and grafted many different varieties on the tree, you can then sell it.
