This is a great quote from Karl Poyani, in The Great Transformation:

The outstanding discovery of recent historical and anthropological research is that man’s economy, as a rule, is submerged in his social relationships. He does not act as to safeguard his individual interest in the possession of material goods; he acts so as to safeguard his social standing, his social assets.

This idea is central to the concept of an anarchist gift economy, and it is great to see a non-anarchist historian talk about it. I’d love to read more about research on this idea.
