Is the author's point that the political views in question are not popular? I thought he was attempting to make the point that the economic system personified in the execution of those political beliefs is not efficient.

Which if the last decade plus of cryptocurrency has taught us anything, we ought to be able to thoroughly discard by this point in time.

I am aware that the political orthodoxy of the time is popular and the view that it should be discarded is unpopular, aside from observing that this would be true of basically any time and place, I have no further comment on that. My point is that the alternative simply flat out works better. I have zero care or interest in what is popular.
