> Not really, worldwide production capacity is several magnitudes below what would be necessary to buffer a large renewable rollout.
Which definition of 'buffer' are you using here? Enough to supply day to day drops, or some kind of year-round system?
Wind and solar would need to scale up two orders of magnitude, and it's not hard to imagine batteries scaling along with them. How many more orders of magnitude would batteries need to scale up?
Current battery production is tiny, services small consumer electeonics and some cars. It's at least two orders of magnitude.
Day to day drops are realistic, but buffering from summer to winter is out of question really.

That is 100% fine. It only has to scale as fast as the power production. If they're both scaling two orders of magnitude, they should work hand in hand just fine.

Good! Day to day is all you need. It's ridiculous to use batteries between seasons, and there are far better technologies to use.
Battery production needs to scale about two extra orders of magnitude- current production can't backup current renewables.
The current battery prices are reflective of relatively small spale, high value needs of consumer electronics industry and a nascent electric car industry.
Hopefully the price will drop massively, like it did for solar panels, but currently we can't even produce enough for cars
