Agreed, there are tradeoffs. But from a principled perspective I recognize the risk in having to choose between escape and home power. Adverse events often stack in unexpected ways at the worst time.
I get your point, but let's assume that you had separate resources for escape and home power, and then you needed home power for an extended period. Wouldn't you like to have the option to be able to use your escape resources to power your home?
I think so, but the tail risk impact is still worrisome. Guess it also depends where you live - I’m in a fair weather state, so powering my home is not a survival issue for the most part.
If I lived in eg Texas, I’d maybe have a BEV that could power my home and a separate vehicle for long range travel. Bit of a luxury.
Money is limited, so sharing resources between situations lets you be prepared for more situations.
