Here is the problem with your analysis.
Since Andrew (are before) the codes have been made much much stiffer. You can't build the way you once did years ago.
In fact many people in northern and central florida were in LOW risk areas and had far worse damaga that south florida which took a direct hit.
N.O. had no hurricane codes which is why many of their homes are just plain gone.
The insurance companies want to charge as if there is no code improvement. IOW they want to charge a high survival concrete block building as if it is a wood and tar paper shanty.
You complain about burden of choices, but much of this debate is about the fact there is no BENEFIT OF REWARD IN SMART CHOICES.
Discounts in crumbs is no discount.
Sounds like a great opportunity for a insurance company to make some money by insuring only post-Andrew homes.
Oh, but wait! The regulatory agencies won't let them do that! Because it's "not fair."
So post-Andrew home owners are screwed just like people who pay more to live in non-flood planes, etc.
The problem is the market is not a free market.
Does current Florida law allow the insurance company to take construction into account when insuring an individual property?
Wrong, but a good attempt.
