Parent was just spreading a lot of fud, half-truths, and "yeah, maybe if you squint and force an exotic framing"... they're trying to convince you to throw the baby out with the bathwater, don't lose sleep about it.
I would like for you to offer a rebuttal other than it being fud and exotic.
I would argue that Vermont is an exotic example of where batteries offer disproportionate value. A city with a single privately owned monopoly supplying power and able to import power from nearby hydro, coal and nuclear plants.
