But this approach just wouldn't benefit some popular dance clubs. Without a solid door policy clubs would be stuffed with people who come there for wrong reasons. To pick up girls, to get drunk, to visit an attraction for the sake of a visit (not because they enjoy techno music), to get into a fight, etc etc. Have you ever been to a poorly managed club? They don't have a community, don't focus on a holistic clubbing experience, have many people with really bad vibes. Would you want to stay there for a night and the next day (night time + day time raves)?

Let's be honest, techno is not underground in Berlin, these clubs are a massive tourist attraction. Berghain is not a 50 person dive bar in SOMA.
