alt Hacker News> Sure, it might cost more
I think this is more than good enough to be the "straight answer" you're looking for all on its own (& it's definitely not a case of "it might" - it definitely will).
However, on top of the cost, there's three additional reasons:
2. It will take longer
3. It will need to be geographically distributed to an extent that will incur a significantly broader variety of local logistical red tape & hurdles
4. One of the largest components that will cost more is grid balancing energy storage, which is not only a cost & logistical difficulty, but also an ongoing research area needing significant r&d investment as well.
Given all those comparators, it's a testament to the taboo that's been built up around nuclear that we have in fact been pursuing your "all renewable" suggestion anyway.

You're wasting your energy on that user, I suspect.

...is commonly a rhetorical pattern meaning "I've predetermined my conclusion, but I want to save face by appearing rational and casting those I disagree with as biased or incompetent in one fell swoop."
It's the "Aren't there any REAL men anymore?" of contentious topics.

Longer than nuclear? Where did you get that idea from?
Anyway, about #4, nuclear can't economically work in a grid with renewables without batteries. With renewables, you can always temporarily switch to a more expensive generator when they go out, but anything intermittent that competes with nuclear will bankrupt it.
