There would be two things necessary for such a realization of a pure gift economy:
- Greed must be tempered
- A post-scarcity society
We have to temper greed, because that is the first prong in tackling scarcity. Scarcity can be tackled next with automation. In order to do this, our thinking and value systems have to change. Capitalism is more than just an economic system--it's a value system. Not only did people give form to capitalism, capitalism also gives form to them. A system can create it's own evangelists.
To break the grip capitalism has, we have to destroy it's value system. Marx made the excellent philosophical observation of how economic, political and social systems work holistically--the individual influences the system and vice-versa. Combining this with the concept of memes from Dawkins (which many of you hate, I know) and one gets an idea that there is some kind of oscillatory momentum set up between the memes themselves and those conveying them that serves to explain why bad ideas stick around, despite being detrimental.
TL;DR: The gift economy is ideal. It also only feasible if you are post-scarcity. You can't really get to post-scarcity unless you are post-greed.
I am a pessimist by nature. Many people can only keep on fighting when they expect to win. I'm not like that, I always expect to lose. I fight anyway, and sometimes I win.
