To support my belief in the arbitrariness of economic theory and thought, since different economic systems have their own rules, theories etc., which contradict the rules of other systems and which most of I think are authoritarian (because they're enforced over groups using politics),
does there exist school(s) of economic thought that is about "no economics" or "no economic theory"? Or perhaps no economics in the sense that "all economic theories (e.g. capitalist, communist ...) at the same time".
Or in other words, is there economic theory that's non-political, i.e. does not require politics for functioning?
