OP's "the people wanted this" hints at a complicated background. Getting out of nuclear is a long-running social movement in Germany, with Chernobyl as a decisive event. There's a caste of of politicians and private individuals for whom this is generation-defining/a founding myth. It's the kind of thing that arthouse movies (e.g. "Das Ding am Deich") and social documentaries are made about. Discussing, for example, the particular issues of adolescents raised by parents who used to live at the protests parties in the 80s.

It bubbled over with Fukushima, the a roiling and boiling mid-life crisis for an entire subculture. Consequences or the Russia variable provided little resistance to the Zeitgeist - the biggest "I told you so" in decades. There was no planning to be done.
