Hurricane Ida, like all hurricanes of that magnitude, caused substantial damage, and the ignorance abounds after the event. Comments on news reports are full of the usual anger about government rebuilding with public money, and the damning of the individuals that live in in hurricane prone areas.
Government assistance ends after one claim. Help from FEMA, which doesn't allow enough money to rebuild, requires those that were helped to acquire insurance, or take the chance they won't have damage in the future. Otherwise, since there have been enough major hurricanes along the Gulf Coast over the last twenty years, the rebuilding costs are mostly covered by insurance. The same goes for flood prone areas. The result of this is either relocation by individuals, or the demand new buildings follow strict building codes, and hefty insurance costs.
In the end, damage from hurricanes leads to higher real estate values. If there is a known economic advantage to rebuilding, it will happen. Property that is no longer viable for development is abandoned. This can lead to pricey vacation property, and the cottage industries that supply those with enough money to invest in the real estate. Businesses in these areas already know the stakes, and stay because the demand for their services outweighs the risks. The costs to stay are included in the prices.
Another thing: People stay where they know the area, or cherish their hometown. Generations of families may continue their heritage, or keep a family business thriving for those that either enjoy a hurricane prone area, or have work that demands the proximity to the coast. Usually, these types of people are more self-sufficient, have strong family roots, and really don't care what anyone else thinks. They don't ask for any special favors, and can take care of their own. Belittling them shows ignorance, and a lack of character.
