When I read word “bargaining” I assume that we are talking about entities that have preferences, action set, have beliefs about relations between actions and preferences and exchange information (modulo acausal interaction) with other entities of the same composition. Like, Kelly betting is good because it equals to Nash bargaining between versions of yourself from inside different outcomes and this is good because we assume that you in different outcomes are, actually, agent with all arrtibutes of agentic system. Saying “systems consist of parts, this parts interact and sometimes result is a horrific incoherent mess” is true, but doesn’t convey much of useful information.
