Once again you are pretending to demolish straw men of your own construction.
We've been here before Sub - you are presenting caricatures of unidentified "literary / upper & middle-class / academics" and putting analyses that no longer exist, if they ever did.
When asked, the source singers have defined the songs we have chosen to call "folk". 54 is no more than an attempt to bring some sort of consistency to what we have learned - if you don't accept what we have come up with, offer your own.
Once again you prove the old construction trade adage that it is always easier to pull down what somebody else has built than build something of your own.
You folkies really get me!
