You want demand to adapt? I'm supposed to turn the lights out when the wind's not blowing, or what?
Demand shouldn't adapt, supply should adapt. Connect more and bigger power grids, add energy storage to the grid in large enough quantities.
Your "solution" is like telling people to give up cars. They won't.
In cold climates people have increasingly well insulated houses that are relatively affordable to heat, and mostly use non grid electric heating. And can also shift power usage around the day because it takes a day or so for the house to cool uncomfortably.
You may argue that the current value of the base load is artificially high, but there obviously is some fundamental base load given by the kinds of consumers you have.
With distributed generation and storage, yes, it's plausible to have periods of 0MW grid demand.
> there obviously is some fundamental base load given by the kinds of consumers you have.
The kinds of consumers you have are not a fixed quantity; particularly their on-site use, generation, and storage patterns all vary over time.
If not, than you must accept there exists some necessary base load. That can be provided from base production like it is today, or it could theoretically be provided from storage and over-production in a hypothetical renweables-only grid.
Seriously.

Yes it is. It's a law of human nature :-)
Yeah,base load still exists as in the dictionary definition (floor of aggregate power supply and demand), but it ceases to be a fixed level that is a hard production quota.
