If you have gigawatt-sized gaps to fill in non-fossil generation, then it doesn't matter that something doesn't scale down, it's a problem if something doesn't scale up. It doesn't matter how much a single wind turbine costs, it matters how much a gigawatt of wind turbines costs and where you will place all of them.

Exactly. Cheap wind and solar electricity is useless if it isn’t produced on-demand.

It still blows my mind that so many have such a hard time grasping such a simple and fundamental concept.

Because it's just wrong. In any grid you always have at least some form of demand side management. Dispatchable consumers.

Add enough storage to the system and the on-demand problem is solved.
