Ultimately cost is just one factor to prime driver like energy, energy security most overwhelming priority in energy trilemma (security, cost, sustainability)... Having dispatchahble power not tied to weather with abundance fuel source is always going to trump all other considerations for any serious grid. PRC got burn going ham on renewable a few years ago, few heat events that fucked over hydro production, increased AC demand and all of sudden you're dealing with opportunity cost of rationing factories that currently far exceeds $ differences in generation. Theoretically countries can size renewable rollout that minimum intermittent power + storage can reliabily power grid even with current tech, but that's like... multidecade megaproject.
