The market was wrong so many times that using it as a source of ultimate truth sounds like a last ditch argument. The same market that still goes for oil and coal and would have barely touched EVs or clean energy if it wasn't for subsidies.
You either didn't understand the problem or are just like anyone who ever said "why invest in clean energy when we have perfectly good coal and oil today, and it scales". We did and now we reap the benefits of clean energy. There is no reason to not invest in getting even better, even if this requires research. But I think you just see the label "nuclear" and any reasonable argument based discussion flies out the window.
In the mean time Germany is closing nuclear plants to burn coal. Lungs rejoice.
