The minimum conditions for positive reciprocity are particular to an exchange (via positiva, scale dependent), whereas, the minimum conditions for negative reciprocity are universal (via negativa, scale independent).
Universal aversion to the imposition of costs on demonstrated interests (negative reciprocity) does not assume a particular portfolio of interests—property—but accounts for variation in the conditions of positive reciprocity at the interpersonal, group, civilizational scale.
IOW: group variation in the expectations of positive reciprocity are secondary to the universal law of cooperation: negative reciprocity. Civilizations vary in the former by adapting to the latter in different geographic, demographic, economic, political environments
