Because one of the ....ummmm.... 'features' of folk is that, like egg painting and curling and collecting samples of barbed wire, it does not feel the need to appeal to the majority of people..(who, in large groups, tend to distort and muddy the basic points to fit their personal ideas of what music SHOULD be.)

It is already the case that the definition of 'folk' has been expanded and diluted so that $$$$ can be made by people who are bored by the basics, but like the idea of not needing expensive costumes & huge speaker systems to put out some sort of vague approximation of what they think it's all about.....and then to gratuitously change certain components in order to have the NEW pieces identified with them.

(No...they don't all do this as a 'plan'. Many are quite unaware of how they are warping the process thru mass media.)


Any more questions? ☺
