Two years ago I'd agree with you. Today I'd be concerned that an executive order would direct FEMA not to help out of spite against CA politics. I can already hear the arguments, blaming us for living in a high risk area.
That argument is true though.
Build your house on the beach, a flood zone, top of a cliff, wherever. And insure it.
But don't expect the taxpayer to subsidize your risk. (Though I suspect they are...)
