Not that different from 'effective altruism', really. Maybe running a Ponzi is moral if you are taking the money from people who are not effective altruists, but you are saving the planet or something?
Or Kant's categorical imperative, act in a way that you would want to make universal law. Then in order to act morally, you have to solve for all downstream impacts of the action over all time, if everyone acts that way.
Seems computationally intractable, possible multiple local equilibria, problems with which discount rates to use and whatnot.
Hence the popularity of simple ethical systems, just do what God says on the tablets and be done with it.
That's the cool thing about shaky theoretical foundations and fuzzy data, you can project anything you want onto them and act with a great deal of moral certainty about everything.
