From an economic viewpoint wind is baseload, as the fuel is free. But its reliability is many orders of magnitude lower than in conventional sources.
So essentially the more capacity based on wind you have in the system the more intermediate and peak capacity you need.
But the utilisation of the capacity will go down.
not that anyone in their right mind expect wind to be alone in a sustainable grid.

It is easier to find countermeasures, but that needs more reserves.
All that is required is to lower the average load factor of the fossil fuel plants, i.e. burn less fossil fuels in order to burn more solar and wind. Financial compensations are no doubt needed to those plants, to cover the sunk capital costs.

That's not a mix-up and not physics, but the separate issue of providing balancing capacity to meet the difference of demand and total baseload production. And how does that not apply to conventional baseload? Baseload never meets demand anywhere near 100% of the time, and the difference can be rather big on occasion (be it a cold spell in a region with lots of electric heating boosting demand like in France in February this year, or a total shutdown of 52 nuclear plants following a natural disaster and subsequent safety concerns like in Japan earlier this year).
