Hmm, while your statement is technically correct it is also ignoring all of the hype around Tesla's "whole house battery" technology which is, as part of its positioning in the market, turning grid tied installations into more stand alone installations. And yes, it is "thousands of dollars" cheaper to do a grid tie system, and yet the regulatory changes are making it harder on home solar systems to recover costs (mostly because it shifts peak load costs toward the utility and away from the individual rate payer, the utilities are trying to avoid that).
And the article is discussing a "future" world where almost all individual houses are not grid tied, rather they are perhaps grid backed up, in the event that there isn't enough solar or wind to keep their house batteries up.
So in that world, where folks are converting their "old" grid tied system to the "new" grid independent systems, it is going to change other parts of the community that break when external events disrupt the grid. That will mean that communities will be less impacted by the "grid" getting knocked off line by a hurricane because their normal mode will be to not be on that grid. And that has some positive implications for community planners.
