My point is that scaling coordination issues exist for everything, including all sources of energy production.

Singling out solar and continuing to not prioritize it will inevitably lead to ongoing grid issues. Whereas this has been mostly solved for other sources, due to lobbying and legacy. Thus my confusion about the OPs half-baked point.

If you go up the thread, this is the context we're in:

"Solar can be deployed by hundreds of thousands of individual efforts and financing at the same time, with almost no bureaucracy."

N>100000 is a lot harder to coordinate than the ~15,000 established power plants, which have come online over the last hundred or so years.
