Anthropologists have argued, in contrast, "that when something resembling barter does occur in stateless societies it is almost always between strangers."[6] Barter occurred between strangers, not fellow villagers, and hence cannot be used to naturalistically explain the origin of money without the state. Since most people engaged in trade knew each other, exchange was fostered through the extension of credit.[7][8] Marcel Mauss, author of 'The Gift', argued that the first economic contracts were to not act in one's economic self-interest, and that before money, exchange was fostered through the processes of reciprocity and redistribution, not barter.[9] Everyday exchange relations in such societies are characterized by generalized reciprocity, or a non-calculative familial "communism" where each takes according to their needs, and gives as they have.[10]
But the harm may go deeper than a mistaken view of human psychology. According to Graeber, once one assigns specific values to objects, as one does in a money-based economy, it becomes all too easy to assign value to people, perhaps not creating but at least enabling institutions such as slavery (in which people can be bought) and imperialism (which is made possible by a system that can feed and pay soldiers fighting far from their homes).
Freegans are people who embrace community and sharing, in opposition to a society based on materialism and greed. Freegans avoid purchasing new products or food as much as possible. Instead, they spend a lot of time digging through trash and waste, looking for the things they need. Yes, it’s an extreme example of sharing and bartering, but they make the system work for them!
mid-15c., apparently from Old French barater "to barter, cheat, deceive, haggle" (also, "to have sexual intercourse"), 12c., of uncertain origin, perhaps from a Celtic language (cf. Irish brath "treachery"). Connection between "trading" and "cheating" exists in several languages. Related: Bartered; bartering. The noun is first recorded 1590s, from the verb.
Many prepper fiction novels eventually get to a point where there is a barter economy or the characters visit a Trading Post.  For instance, a trading post plays a prominent role in Mark Goodwin’s series, Seven Cows, Ugly and Gaunt: A Post-Apocalyptic Saga of America’s Worst Nightmare.  In the novel, the characters use silver to purchase the necessary items to survive and make life easier.  Goodwin’s novel is a post-apocalyptic EMP story.  The poop has really hit the fan in this one!
Bartering is the trading of one product or service for another. Usually there is no exchange of cash. Barter may take place on an informal one-on-one basis between individuals and businesses, or it can take place on a third party basis through a barter exchange company. A barter exchange is any person or organization with members or clients that contract with each other (or with the barter exchange) to jointly trade or barter property or services. The term does not include arrangements that provide solely for the informal exchange of similar services on a noncommercial basis.
In the United States, Karl Hess used bartering to make it harder for the IRS to seize his wages and as a form of tax resistance. Hess explained how he turned to barter in an op-ed for The New York Times in 1975.[31] However the IRS now requires barter exchanges to be reported as per the Tax Equity and Fiscal Responsibility Act of 1982. Barter exchanges are considered taxable revenue by the IRS and must be reported on a 1099-B form. According to the IRS, "The fair market value of goods and services exchanged must be included in the income of both parties."[32]
Bartering is the exchange of goods or services. A barter exchange is an organization whose members contract with each other (or with the barter exchange) to exchange property or services. The term doesn't include arrangements that provide solely for the informal exchange of similar services on a noncommercial basis. Usually there's no exchange of cash.

People in nearly 14,000 cities spread over 182 countries are waiting to rent you a room, apartment, or home wherever you’d like. Since 2008, Airbnb has made it easy for you to find a place to stay wherever you may be headed. Just enter the dates you need, see what’s available, and book your stay. The site even has its own payment system, protecting all parties from fraud and illegal activities. While you may at first only be interested in traveling, you can eventually sign up to be a host for other members. There are no fees to join, and Airbnb keeps a small portion of the host’s price of each stay to operate the business.
When two people each have items the other wants, both people can determine the values of the items and provide the amount that results in an optimal allocation of resources. Therefore, if an individual has 20 pounds of rice that he values at $10, he can exchange it with another individual who needs rice and who has something that the individual wants that's valued at $10. A person can also exchange an item for something that the individual does not need because there is a ready market to dispose of that item.
