alt Hacker NewsYou can drive a $30K car and have a $10K backup power system.
An $80K-100K car that replaces the two isn't some genius purchase.
Sure you can spend all the money you want on a luxury toy, nothing wrong with it, but it's weird trying to justify it as anything but that.

What you've shown is that there is a crossover where a gas car + generator beats an electric car.
That doesn't mean electric cars shouldn't be considered as power backup, or that buying a nice electric car vs a nice gas car doesn't come with the added benefit of "Don't need a 10k generator anymore".
An Ioniq 5 is not a $80-100k car, though. The difference in cost between it and an equivalent gas car is less than $10k.
I have a champion tri-fuel that cost < $1k which runs essentially my whole house. It's plumbed into my natural gas so as long as that is up (it has never gone out), I don't even have to refill it.

See, your problem is assuming that the EV is 80-100K. Or that the ICE car is 30K. This is a contrived comparison. An average new car is well over 30K. And I bought a brand new Lightning for 50K. Being able to use 131kWh of battery for things other than driving is a pleasant bonus, and I prefer it to having a gas generator I have to keep maintained and store fuel for.
That $30k car could be an EV, too, and be part of the backup power system.
In Australia, $10k would buy not only a ton of solar panels but also batteries. The US has decided to make solar and batteries at the home super expensive, unnecessarily.
