"No," Sergei said. "I mean I like money. I like exchange. Abstracted exchange. Simplicity. You give me something, I give you something. We're quits. You don't have to decide what kind of person I am, if you like me, how distant I am from you in social space. We could be masked strangers in a privacy zone. You want something from me, you give me money. I don't care who you are. I don't care what you want it for."
