It's how the economy worked in Australia before colonisation. It was explained to Me by an Elder from the central desert. Before colonisation, there was no word for work. There was a word for sweat. You put sweat into helping your community because you loved your community. Karl Marx explained it a little differently; he said: From each according to ability, to each according to need.
David Graeber wrote this book called Bullshit Jobs. A bullshit job is a job so pointless, even the person doing it believes it has no purpose. Some people with bullshit jobs don't even have to do any work. They just sit in an office all day browsing Reddit and pretending to work. Graeber thought these people would be happiest, but they're not. They're depressed and unhappy. Turns out, humans have a psychological need to contribute valuable work to society. They need to help others.
A gift economy is the natural and proper state of humanity. Trading work for currency tokens is a dangerous aberration. Groups who live and work together don't need to barter in order to cooperate. If you take people out of the capitalist mind prison, a gift economy is just what makes sense. We already have communism for children; we give them food, housing, clothes, and an education for free. But it takes a village to raise a child. So imagine if everyone in your community just helped each other the way we help kids. That's communism.
