the idea is that everyone knows the idea that nobody owns anything, so they’ll boycott that person with zir rotting fruit and stop delivering their own stuff to zim so this person with the irrational mindset will have to confront that ze’s ostracized. (of course, ze could still steal stuff from them if ze wishes, but ze no longer have the social feelings of receiving a gift.) if there are no apples anywhere else they’re supposed to revolt and take the apples by force because of how used they are to the status quo, and if that person wants ze can start a hermit life somewhere else and ask for people to join zir quest about rotting fruit
