BESSFID (the common initialism? Not sure!) does not track interlock failures, which after them falling on you is the most directly dangerous aspect of both battery walls and standby generators. Unexpectedly energized lines are not something an average user understands, which is why it's responsible for so many dead linemen. Generators (and now battery walls) feeding back into the grid during an outage are the #1 cause of unexpectedly energized lines, and this is very basic knowledge. It's why every municipality requires a generator interlock be installed at the box for home-consumption power generation. No grid in the world is yet robust enough to prevent this danger.

[That batteries wear out] is true at any scale, resi, C&I, or utility

Yes and no! While yes batteries will always wear out, municipal facilities are not restricted by things like space constraints or residential safety concerns. This means they can implement battery degradation mitigation techniques that are impractical (or feasibly impossible) to be implemented on a residential scale, like distributed cell charge/discharge limits (which at their most effective handicap residential units by up to 20% of their rated capacity but greatly increase the lifetime) or direct cell cooling (which benefits spectacularly from economies of scale - active cooling on small packs is a huge drain for little return, but large scale battery installs can even use geothermal cooling to additionally increase their efficiency). Neither removes the fact that cells do wear out, but it greatly reduces the rate at which they do, and at a significant energy and space savings over alternative techniques. (You'll note that these are many of the same reasons that municipal standby generators are more efficient than large numbers of residential standby generators!)

(this bit is mostly responding to your personal attacks, I will admit that:)

Recycling is projected to increase [...]

Yes, but I am talking about current battery technology. You're rebutting comments I made criticizing current technology with projections and speculation about future technology, which just isn't fair. I could (hyperbolically, I admit) do the same thing by speculating that giant lithium eating termites will be developed by some rogue nation state in the near future, and that having a power wall risks them being attracted to your home and consuming your family in a gore splattered orgy of B-movie tropes.

Sure, let’s throw away one of humanity’s better solutions to the climate crisis since it’s bad now. It’s not like it could get better in the future. Again, such a show of shortsightedness.

A similar thing here. You're also assuming that the future will improve things, which while it's laudable you're still able to be optimistic (no I mean that, I'm a depressed pos) it's also very biased to assume that things will improve as time goes on.

You’re using the argument that the perfect is the only solution to the imperfect, when that shortsightedness gets in the way of progress.

And again, but with the additional add-in that I repeatedly say that municipal installs are better than home installs, not that batteries as power storage solutions are inherently bad. Just that the technology for home use, right now, is.
