My point is that immediate profitability (eg nuclear being expensive) is not the right metric. It matters and it's a part of the equation, but overall, it's a bit meaningless to say solar is more profitable to a capital investor than eg nuclear, therefore let's base a country's grid on solar power alone.
Your link to Poland is one of my key counterexamples to a full renewables grid. Northern Europe absolutely sees long periods with little sunshine and wind, and that's also when its energy requirements are highest (winter heating). Much of it is flat, too, and seasonal battery storage exists nowhere right now.
So... If not solar or wind or hydro, and want it to be low-CO2, then you're short on options. So exorcising nuclear seems a bad idea.
