@neonsnake The way I see the divide between the gift and the market economy is
* There's enough wealth to go round, if we share it;
* We need to support those who are unable to earn, anyway;
* Obsessively tracking flows of value is very inefficient -- it takes a lot of otherwise unnecessary work;
* Property and markets disentropise wealth, which you then need a taxation system to redistribute.
In other words, there's a lot of practical disadvantages to markets, for little obvious benefit.
