It is indeed "not community dancing", but professional cultural activity (or "show biz", if you like – so is a performance of, say, Beethoven). It does not claim otherwise. Similar acts exist in contexts of English, Irish and American folklore, not all of highest standards in terms of authenticity and artistic quality, and, as it seems, fewer than in many other countries.

My point is that such performances are the cream on top of a very broad culture of unpaid eager amateur efforts – and of equally dedicated fans. Nothing wrong with community fun, but don't begrudge those who are more ambitious. Many of us "Didn't meet commercial specs" but still find it rewarding.
