Come on, they are not. One is a value system, the other is a technology/practice.
As economist Stevie Wonder once said, "When you believe in things that you don't understand Then you suffer Superstition ain't the way"
I think it's too much of a stretch to label anything "irrational" as superstition.
I think both the purported benefits of the shareholder-theory-of-value and fictionalization rely on plausible-but-false belief in the outcomes created by the 'invisible hand'/selfishness-at-scale, but I wouldn't call it superstition, just wrong.
Also, I think the connotations of words are pretty important, and there are a lot of words that for the most part mean the same thing with different connotations. If I had to describe the connotation of superstition, its an action believed to have an effect, but that effect is a total non-sequitur. At least with what we're talking about, there's at least a plausible basis for believing the effect will happen, even it that basis is wrong.
For those who aren't inside the club, those are superstitions.
