If you want a new economic model and new purposes for it you have to look for its major outness (money, debt and banking), discern the paradigm concept of that outness and then replace it with a new concept that fits seamlessly within the legitimate structures of the pattern under consideration and yet changes its character while resolving its major outness. The means of that new conceptual implementation requires a new insight or insights.

This is the scientific, philosophical and paradigmatic process. All else may be legitimate research, but at best is only palliative reform and at worst habitual abstraction and regurgitative erudition.
