I've long stopped believing the smartest people in the world accomplish much at all besides doing extremely well in systems others have designed. Certainly the vast amount of time I've spent thinking about monetary policy offers me no real gains in my life. I know a group of medical doctors and they are brilliant, but they are brilliant
critics.
They are smarter than me - they focus on what matters. Small things, that they can control. God forbid the world does fly apart at the seams, and maybe some of these epistemological economic thoughts will have been worth thinking - I sure hope it doesn't happen and the smartest people can continue living in tiny boxes. It means a better world, a more stable world. And we do need smart people studying a set of ligaments their whole lives.
I find it no surprise that those of us who grew up in extremely chaotic situations tend to think 'bigger' and have a harder time thinking 'smaller'. I do not know the world will remain stable enough to support my career - but all the doctors I know are sure of it.
You'll get replies from very well employed, very smart people, who can probably write you an excellent simulation of our discussion, but who will refuse to conceptualize an abstract theory of value, or a world were currency creation happens in a slightly different way. Why would they? It's of no practical value unless the world ends - and you don't want the world to end, do you?
People who fought for monarchy because the alternative is chaos were probably smart people. People who fought for heliocentricism were probably very smart, but didn't feel like uprooting the foundation of their world view. Being dumb enough to think thoughts like "well, but what if", in the face of replies like "but it hasn't in a long time!" is only useful if only a tiny subset of us do it. The right strategy for most humans is to ignore that kind of talk. So be it.
