So do we just wave a magic wand and suddenly nuclear power does not cost anything. The article clearly laid out the cost and why even with deregulation LWRs are not cost competitive (while other technology is just not there yet). Or is your argument the government should even heavier subsidise nuclear to make electricity cost nothing? But why electricity and not e.g. housing?

Realistically the quickest way to get to the stage where you don't need to think about your electricity usage is put a solar installation on your roof + battery. Now you have to invest up front (and it might not even be a good investment), but it shows that nothing comes for free.
