Your other argument about cheap labor is completely ignoring principle 3. above. Saying cheap labor for an industry is _inherently_ good is basically saying we should go back to the dark ages. This is probably the only principle both capitalists and socialists agree on (at least our 21st century brand of socialists that hope for a UBI utopia)!
Anti-nuclear has almost taken on a religious fervor that I don't understand. Safety is a property of an implementation, not a fundamental law of nature. Please! We're arguing for the same ultimate goal!
It has not been demonstrated that the diseconomy of scale in SMRs is actually tolerable. The experience at NuScale is not providing much comfort there.
Of course the lower demand for skilled labor is good. "Civilization advances by increasing the number of things that can be done without thinking about them." The simpler the task, the less training is required, and the faster workers can be brought up to speed. The high skills needed for nuclear work are one of the reasons nuclear builds are in trouble.
(You might object to that if you are a skilled laborer feeding off this trough. Well, too bad, the purpose of energy isn't to employ you. You are a cost, not a goal.)
Nuclear has taken on an religious fervor that's not based anywhere in reality. Nuclear is demonstrably a failure, yet the proponents are blinded by their dogma.
