I won’t aim to change your mind but I’ll add that one of the reasons they’re so expensive is, at least in the US, there is simply a struggle to build mega engineering projects. From project management to the blue collar skills required (nuclear isn’t the only large scale engineering project with cost overruns). Things were more favorable in the 80s when plants were built somewhat regularly and the country had collective experience completing these projects.
Renewables are similar too on both the installation and design side. More experience in manufacturing, developing, and installing helps to lower costs.
