You didn't read my whole comment there. One could use green hydrogen.
Ah yes. It's a thing that
- can be cheaply produced at scale
- can be easily transported to large distances
- infrastructure can be easily and quickly converted to using it
Note that the application of green hydrogen I'm talking about here, grid backup, does not require replacing existing natural gas use with hydrogen. Nor does it require long distance hydrogen pipelines.
There's no "but". The situation right now is that starry-eyed proponents of renewal energy sources claim that they have already surpassed nuclear etc. When in reality they can't cover the basics. And the answer to that? "Oh, yeah, sometime in the future there may be something to complement this".

Ah yes. Because green hydrogen just magically appeares every time you need it when you say "green hydrogen" three times
I am being extremely sarcastic, that's true :) For all the reasons you listed :)
So, back that up with burning natural gas.

So, the "cheap" is in reality:
- many gas powered energy plants (that are not there, and need to be built)
- plus many batteries (that are not there, and need to be built)
- plus cheap natural gas to burn
So much for "green energy already has the capacity to replace something"
