I bet a lot of people have the guts. They just don't know how because there is no mechanism in place to make it feasible. Back in the 70s there was a very nice Jewish man who was setting up an alternative barter system that would allow people to trade goods for goods. I volunteered to give massages and received a very nice diamond ring from a pawn shop. And I still owe somebody somewhere a massage. It was a great idea that never took off. I am much better at it now.
