It's very simple, Villan. You made it clear from word one that you would only let people play in your venue if you thought they were good enough. What you are doing is taking folk music (and neofolk that is performed in the same setting) away from people, leaving it to their gurus, putting yourself between the people and the music, and setting it up on a platform to be passively consumed. That's the music business ethos, even if you do not personally profit from it.
