Our proposed system rapoptosis is a novel proposal for the sustainable value of artifacts. It aims to enable unused things to autonomously determine their own existence value, bid farewell to their owners, and be revalued by new or original users. In this paper, through the questionnaire survey, we define the existence value includes not only measurable extrinsic existence value but also intrinsic existence value such as memories and attachments. In addition, through the workshop, we investigate the appropriate form of farewell and various farewell messages, and summarize the design guidelines for the autonomous farewell of artifacts for revaluing of itself.
