Is the world becoming uninsurable?

American, living in area prone to natural disasters: "Is the WHOLE WORLD becoming uninsurable?"

The answer is obviously "no" since there are other parts of the world that don't live on a hurricane highway nor build houses made from firewood in an area prone to wildfires.

Do we know why the insurance companies can't simply raise the insurance price to match the risks in those areas that are prone to natural disasters? I mean in general, not as in California where the government imposes strange policies. Speaking of the policy, why wouldn't California allow the insurance company raise the premium by region? Doesn't such policy benefit the rich at the cost of the poor as the rich love to live by the hills, lakes, or beaches, which is very much against the ideology of California?
