Not so easy to reduce the grid load all the time, needs a big battery for every night and for multiple dark days you still need the grid a lot.
Take the Texas ERCOT market, which is the closest thing to a free electricity market that exists in the US. A huge chunk of new grid assets are batteries, becuase they are one of the most profitable things to install right now (see the map at the bottom of the page)

Additionally, many people are now buying EVs, and an EV stores 2-5 days worth of electricity. If big batteries on wheels are commonplace, then simpler and cheaper immobile batteries are pretty easy too.

The solution of course is more batteries, but you can't really incentivize non-peak generation until you get the batteries. That's part of the NEM3 change that the blog mentions, to change the incentives from just solar to solar and battery.
Large neighborhood batteries seem to make a lot more sense to me than batteries in every home.
Boy people hated their HOA before, imagine how much they'll hate their HOA (because neighborhood batteries would need to be owned by someone, and that someone is the HOA) when they can cut off your power bc you left a garbage can out too long!
