If we went to moneyless transactions totally, what would I do with this hollow mattress?

The point is, 94.924% of the 'convenience' is just for business and banks....not for me.....and bank can't accidently 'lose' money that I have hidden in my copy of "The Illustrious Life of William McKinley"....and *I* can't just treat it as little numbers to be tossed about when I have to go dig it out and carry it to the store to squander it.
