There’s a difference between business licenses and making dancing itself illegal. I don’t know if that’s a real law somewhere in Germany, but it’s definitely further along in restricting personal freedom than requiring a business license to allow dancing in a club that serves alcohol, and I’d be surprised if Germany doesn’t have similar laws.

Although I imagine there could be some very conservative local jurisdictions, in the US, that outlaw dancing in some ways as well.

Having something be licensed simply means that it’s now illegal for you to do that thing.

It’s a euphemism.

Honestly, I feel it must be unconstitutional to outlaw protected expression by people simply because they are standing in a building in which other people serve alcohol at other times.

Dancing itself isn't illegal, just doing it publically, on those days. It's rarely enforced, many places have exceptions that it's allowed unless the local church mess is disturbed due to noises.

Any closed club is fine to my knowledge.
