Even in places with lots of hurricanes the odds of the house "blowing away and falling over" are pretty slim. I speak as a person who grew up in a place that gets a lot of hurricanes. The biggest impact is usually flooding and roof damage.And now, once again, as someone living in a highly tornado-probe area, it's mostly roofing damage. The odds the tornado will destroy your house is still incredibly slim.

So do you spend significantly more for construction for a failure that's still extremely unlikely? Y'all are acting like every time there's a thunderstorm all the houses just blow down. You're entirely disconnected from reality of the actual risks versus massive increase in costs.
