No, we probably should. Barter may work okay for when you have chickens to trade for boots, but you'll soon run into limitations. The vast majority of trades people make depend on some kind of future delivery. I don't want supper to show up when I get to work in the morning. It is much more practical to, instead, accept a token of debt (money) from my employer and then see that the debt gets repaid by my employer later when I go to the grocery store.
A debtless economy would be an absolute nightmare.
