The "renewables can't supply baseload" has been so well debunked that at this point I have zero respect for anyone (typically nuclear stans) still trotting out that argument. No, renewables damn well can supply baseload, and likely cheaper than fission. The question is exactly which renewable sources and storage technologies will end up being cheapest, not whether they can do it at all.
At this point it's a race against the clock and we're losing it badly. If we can't transition to it before it's too late, then that we could do it in theory isn't worth a whole lot.
