How many places are there with solar + wind providing the baseload capacity? I'm all in favor of solar and wind power. But they need batteries to be useful around the clock. The batteries are $100 / kWh, and this number dwarfs the cost of solar installations proper.

Storage capacity has to be built along with solar and wind parks. Its already happening. But more investments are required ("more effective" than nuclear). And the electric grid must be decentralized further to accommodate decentralized storage (from your wall-box at home to industrial storage facilities). And it must not stop at borders.

  No it doesn't and it isn't. If you're working for a grid operator tell me how many TWh you need to sustain a 1-in-20 - A 1-in-goddamn-20 - dunkelflaute in a single large European nation, multiplied by cost of storage. Not the "decline", the absolute cost, and what percentage of GDP it would be. Compare and contrast to military expenditure at a time of near-war. I also know these numbers.
