This isn't a silly argument, this is a problem of allocation of resources.
We could have had mass solar deployment since the 70s. We chose not to, and allocate the money elsewhere. Nuclear will take away billions in public money, put it into the hands of nuclear industries, to get electricity at twice the going rate, maybe, in twenty years. A white elephant and a waste of effort.
Can you explain how that would have worked with the much less efficient and much more expensive solar panels available in the 70s?
