Establishing hubs elsewhere would be good for the rest of the country, too. For example in the coal mining regions that fear getting the short end of the stick in the transition to renewable energy.

Compared to the situation in the US ("fly-over states"), it's still trivial to get to your trendy night time activities: Eastern coal mining hubs are 2 hours or less by car from Berlin, and less from Dresden or Leipzig. Western coal mining is in an area with one of the highest population density of the country. That makes me think that the regular "who wants to move there" argument isn't as convincing here as in the US.
