Transmission and distribution aren't trivial. Under the right circumstances, people can get very attractive ROI periods, not to mention a degree of independence.
I can't be the only one who learned from the Texas incident that our grids our metastable and one bad crash away from a multi-week outage. I can't be the only one who thought "F that, I want a plan B."
If customers need transmission at night, or even once a year, they still need all the infrastructure in place.
Would decide against having a spare tire on your car, just because your traditional 4 tires were still required?
I think there are a lot of valid arguments to have residential solar, but I'm just saying that the big picture economics aren't really there. You have to pay to maintain the commercial transmission and generating capacity, and then pay again for a more expensive redundant local system.

Like if you build a highway and everyone commutes at exactly 9-5 then that dictates how many lanes you need.
In places with air-con, the distributed solar reduces the peak on a daily and yearly basis.
Distributed batteries also help with this.
In grid lingo these are called "non-wires alternatives" or "non-transmission alternatives"
