But back to the topic - a total catastrophic structure loss would indeed be a problem. But from what I've seen, most insurance claims are not for total losses but rather things like water leaks and roof damage that have much higher sticker prices than what it actually costs to maintain/triage/mitigate/calmly repair. I've known people that have submitted claims for ice dams, oil burner blowbacks, new roofs ("wind damage"), finished basement water damage, etc. I will never submit an insurance claim for those type of things, and so it makes sense to at least consider self insuring, especially when rates are doubling every few years.
