The issue with private insurance when it comes to natural disasters is they don't like losing money (understandable) and the climate is changing.
Those two things together mean that this year you could have good insurance that covers freak accidents, but what about next year, or next decade? An area that may have only seen flooding once a century might be predicted to see it once a decade or even once a year.
People still live there. Some people lived there with the insurance coverage for those natural disasters only to see it slowly go away or to be outright cancelled. We can't expect that they all migrate.
