You clearly have a deep understanding of the engineering side of things, but I suggest you may be over-focused on certain scenarios that aren't being implemented in reality. No one is advocating for wind, and nothing else; it will be a mix of solar, wind, hydro, battery storage, etc that will allow us to kick fossil fuels for good.
Uruguay already solved this problem more than a decade ago. That country went from expensive fossil fuel imports, blackouts, and power cuts to energy sovereignty and becoming a net exporter of electricity in under ten years -- and they did it by implementing a stable mix of solar (~3%), wind (~34%), hydro (~56%), and bioenergy (~6%). That's ~98% renewables, no batteries (or nuclear) required.
