Possibly, but that's orthogonal to my comment. Point is that there will still be cities that have to shoulder PG&E costs not because they have fires but because they can't afford to purchase and maintain their own grid, or don't have the political strength to get it done.
Altadena isn't exactly far from civilization. The point isn't that wild fires happen, it's that maybe these little places should go "off grid" so everybody can get a lower price. Everybody but them probably.
