I pulled up a good discussion from 2019 that sheds light on the dilemma of what's FEMA's obligation verses Insurance coverage.
Yup. If places can't be insured then maybe you build elsewhere if you can't afford to recoup the loss. That's my take.
Not at all alarmist and actually something we want folks in Government to consider like war, epidemics, and outside invaders of all types that could affect our life and economy.
