You have a good point. If people can share money (something I did not know) then they can gain trust for other people, and increase their affinity for them.
With that said, however, I relate back to my first post on this topic, which stated that the money does not really have value, and so the whole system is fundamentally flawed.
I realize now, that some people don't mind this fact, while some do. It is a good thing that nothing negative happend to a user if he completely ignores the feature. Thus, all those who like it can use it, and those who don't, do not have to.
