The Revival is a pleasure-based thing with many people delighting in the ballads, the tunes and their performance. If some of this is based on idyllic romanticism, so what!

The research and study is an entirely separate thing though many of us enjoy both the performance side of things, and finding out more about the history of the songs and indeed the people who preserved them.

Again their origins are also separate from this. The oral tradition has nothing to do with origins, only the ways in which the material has been passed on.

Whilst I partially agree with you on definitions, these are and can only be general guide-lines, and for researchers they are very useful, perhaps not so much for those just enjoying the music.
