It would be wrong to say that the city of Berlin is not regulated. What I think is more interesting is to what extent a city creates a sort of safe haven for its users, so that people feel confident that the city works on their behalf.
I think that being in an environment is a much richer experience than just working on a soundstage.
What everybody misses here is that we are doing the same thing my father did. He licensed and litigated and protected his property, and we have to follow the same tradition, because the way the law reads, if you don't protect it, you lose it.
