An alternate currency, denominated in labour time, would prevent profit taking by middlemen; all goods exchanged would be priced only in terms of the amount of labour that went into them as expressed in the maxim 'Cost the limit of price'. It became the basis of exchanges in London, and in America, where the idea was implemented at the New Harmony communal settlement by Josiah Warren in 1826, and in his Cincinnati 'Time store' in 1827. Warren ideas were adopted by other Owenites and currency reformers, even though the labour exchanges were relatively short lived.[17]

Some entrepreneurs are already taking the principles of swapping—use everything and anything you already have to survive—to create another offshoot system, one that turns a hefty profit. Called the sharing economy, it is perhaps best exemplified by Airbnb, a service that enables people to rent out their apartments like hotels. Other sites let you turn your driveway into a parking space, your car into a taxi and your tools into a rental service. Forbes estimates revenue flowing through the U.S. sharing economy will hit $3.5 billion by the end of 2013, and maybe more. It’s worth mentioning that some business associations and government members are terrified of this rise: like most alternative economies, it’s largely tax-free.

In 2012, the average Canadian had more than $27,000 in consumer debt. Wages are shrinking, costs are rising, and one-third of us are living paycheque to paycheque. “Most of us live beyond our means both financially and ecologically,” says Marta Nowinska, founder and president of one of Canada’s largest bartering communities, Swapsity, which launched in 2010. “Swapping is a viable approach to solving a lot of real problems,” she says. Like Simmons, Nowinska left a Bay Street job to join the world of barter. The idea for Swapsity came to her one day in 2006: she was on the subway and noticed how miserable everybody looked. She started to think about a business that could empower people. At first, she thought people could swap jobs, but dismissed it as unrealistic. Then: what if they could swap other things? She developed a business plan and launched a website.
In his analysis of barter between coastal and inland villages in the Trobriand Islands, Keith Hart highlighted the difference between highly ceremonial gift exchange between community leaders, and the barter that occurs between individual households. The haggling that takes place between strangers is possible because of the larger temporary political order established by the gift exchanges of leaders. From this he concludes that barter is "an atomized interaction predicated upon the presence of society" (i.e. that social order established by gift exchange), and not typical between complete strangers.[14]
