I think you should move out to the pole barn now. Try it for six months or a year. Then decide if it's a good backup plan or not.
Also, what happens after the pole barn burns down? Live in a tent?
RV or a singlewide trailer brought in. Ready to go in a day.
it's the paying for it that's the rub...
Actually modular housing, quick fab, could be a huge improvement if made to good code.
Insurance pays for you to check into a hotel that night, but I've had clients in trailers, right on their property so they can watch over it at night while things are being repaired, and yes one in a big RV he rented from a friend.
The bottom line is getting out with the shirt on your back really sucks whether you have insurance or not if your stuff is destroyed. We all know that so we all have to be smart and try to reduce risks where we can. Like never leaving the kitchen while a pan is on a hot stove. Like never putting hot fire ashes down on a wood deck, even in a metal can. Like investing in new house wiring and panels. Like cutting down that rotting tree before it keels over on the neighbor's jungle gym.

Hurricanes and tornadoes don't seem to spare too many people any more. We are having tornadoes in the East where we weren't used to having them. Some call it Global Warming, maybe it's just the weather news blowing so much out of proportion, but if Mother Nature is coming through, she isn't going to ask permission.
one last thought for the OP: make a budget for what you find comfortable, say 500 a year for point of discussion, and ask your friendly local agent how much coverage that will buy you. He/she has to work around coinsurance issues, but he should be able to come up with a solution for you. You may not like that solution, or it may seem like too little for too much. Then either fall back to a homeowner policy with high deductibles, or if you can afford to do so, just maintain personal liability insurance and self insure for property. The only reason folks are objecting to the OP's self insure consideration is concern for him being warm, happy and well fed this winter, versus something much less attractive.
I never did like tents. Nor bugs on my face.
