This is actually a smaller step, as it needs to be approved by the Bundesrat before being effective. This could take month and it’s not guaranteed to pass.
"Nach der Zustimmung des Bundestags kommt das Gesetz am 22. März abschließend in den Bundesrat. Zustimmungsbedürftig ist es dort nicht, die Länderkammer kann aber den Vermittlungsausschuss anrufen und die Legalisierung so verzögern."
Do you think these 180 000 people will be able or willing to join a club? With a mandatory membership fee and legally mandated minimum membership period of three months?
As these clubs are not allowed to hire people and are also forbidden to allow non-members to act on club duties, a membership will mean some work too. How many of the 180 000 are willing to put in that effort.
