You ignore the counterargument I already gave you to what you're saying there.

Nuclear can be made technically flexible. It can't be made economically flexible. The large fixed costs prevent the technical ability you are describing there from being useful. It's pyrrhic engineering, straining to achieve an outcome that's useless. Even France depends largely on the rest of Europe to deal with variations in demand rather than spooling their power plants up and down.

I think I replied to your counter-argument, but I think I did not explain my argument properly.

In the case of nuclear power plants, the expenses are front-loaded in the construction (and the future major maintenance, like reactor vessel annealing). The _running_ expenses are trivial by comparison. So a nuclear power plant saves a much smaller percentage of its cost on a per-month basis when it's not running.

Honestly, I looked at nuclear energy in a lot of details. It absolutely is a viable and economic path forward, but it stymied by the lack of political will. Nuclear projects take at least 8-10 years to complete, so politicians are less interested in pushing them. And commercial companies are hesitant to invest with such long repayment periods.
