Diminished maybe, but not all that much.
I think we can reasonably assume that if there's a huge blackout, it won't last forever. A lot of smart people will work hard on getting things up and running again. A few years ago in the USA it lasted for a bit longer, what was it, a week or two? Recently in Spain it lasted a few days. But all those power stations and power grid operators don't just shrug and go home. So getting through those days is probably all it takes for any reasonably realistic scenario.
And you can build things up piecewise. I've got my solar now. The next thing will be a battery. Once I have that, I can think about an electric car.
