Bartering might show some difficulties in application, however in times of inflation it is probably the only way to survive. In fact the popularity rises gradually. There are even websites that facilitates its applications ( e.g. barterquest.com) where people can exchange not only goods, but also any kinds of services and even real estate. People who looks for specific things are easy to locate and also people who possess what you are looking for. I think it is important to keep the bartersystem alive. Never, never, never forget the things the past showed you, in times when technical modernity fails, we need to go back to it.
