I was looking at bartering form the point of view of bypassing formal money.

For example:
A Grows and sells vegetables for dollars.
A gets B to paint his/her house and pays B dollars to do so.
Instead of negotiating the money that A should pay B to do the job, the bartering entails agreement on the vegetables and quantity of vegetables A should hand over to B to do the job.
Both A and B have something of value to offer and something that they don't have and want which makes bartering possible.
Of course, money as a kind of pseudo store of value provides flexibility while society agrees that it (money) has value.
