Nothing here but lots of justifications for keeping folk music expensive and limited.

Nothing of the sort. There are lots of explanations why folk music is neither expensive or limited. There are lots of justifications here for keeping folk music varied and diverse. There are lots of explanations why your "concept" of free music will ultimately result in less variety, fewer choices and poorer standards. There are lots of explanations why the "barriers" exist only in your imagination.

If you value folk music so little that you are not prepared to spend a single cent on it, then I suppose it will seem expensive. However since you put so small a value on what the rest of us value so highly, why should you expect us to make you welcome? Why should should you expect us to dismantle what works for us, simply to accommodate someone who seems to care so little for music and appears to regard it from a purely sociological point of view, or as an accompaniment to his drinking?
