You've got Nietzche exactly right here as far as I understand him. The problem is, as far as I can see, is that corporate neoliberalism has installed oligopolies which look entirely like pre-modern feudalism​.
And again, Nietzsche​ couldn't have imagined the scale of the problems facing us by mid-century; the ​least of which is a replacement energy source for oil--one which can scale present capitalist societies--that is presently nowhere​ in sight.....
I think it's clear, though, what replaced God: the monetization​ of everything which I argue is a very bad Idea...
