The central idea of this paper is that, P2P is not merely a matter of ”technique,” it also embodies the value of ”co-existence” and ”sharing” of subjects. The mainstream discourse regarding economic intervention overly emphasizes the values of ”exclusionary self-interestness” and ”self-enjoyment,” in so doing the other has been barred from the opportunity of participating the discourse. In this paper, the author takes Smart Mobs as an example to clarify the concrete details of social practice. The author supposes that P2P is potentially able to generate a possible state of ”ideal speech situation.”
