No because I don't give you a gift only if you give me one. It's not a transaction. They are gifts.

...but you turned it into a semantic point. If I farm sheep and you bake bread, it's a market when I trade you wool for bread. If trade even as basic as this can't occur then you're relying on everyone to be self-sufficient.

The alternative is you're expecting everyone to put everything they produce into a kitty which is distributed to all, and I think that is a sure fire recipe for everyone to go hungry and for society to stagnate. There's little incentive to be productive, and no incentive to be inventive.
