Those exist for a reason, care to say why they aren’t necessary before dismissing them outright? Surely you agree some amount of regulation is necessary?
Any set of nuclear regulations that aren't just a copy of France's nuclear regulations are probably too restrictive. France gets 3/4 of their electricity from nuclear without any major incidents.
(Obviously this is overly simplistic, there is a set of natural disasters that France isn't subject to that other countries are, so France is just a starting point. But every addition should be justified by answer the question "What about our circumstances makes us different from France here?")
LCOE is unrelated to systems costs of large decarbonized grid because it leaves out the costs of long-term backup, increased transmission, overcapacity needed to fill the night batteries, and more.
You've made two arguments here, all are necessary and some are necessary. There's a record of anti-nuclear sentiment being stoked by fossil fuel industry[0]
