"Anyone singing a trad song (or a reasonable facsimile) learned from print or a recording (which means just about everyone here, myself included) is at bottom playing a role: that of a genuine trad singer with some kind of social or cultural connection to the essence of song."

That may well be true of many, but of "anyone"? I am sure there are many singers of the occasional trad song who have absolutely no concept of a 'genuine trad singer'.
