Does not answer the question. With no price caps, no one will be able to buy insurance even if required by law. So that means if you own a house in a risky area, you will be unable to sell it and your values will fall. The price caps are to prevent that. But to me, there should be big incentives to prevent building and re-building in risky areas.
So yes, the world in some areas are uninsurable. And other areas are becoming uninsurable.
I very strongly doubt that say Elon Musk or Jeff Bezos wouldn't be able to afford market-rate insurance costs. They would just choose not to because its too expensive. Which is the point of letting the market set the rate
So in reality the burden is falling on Insurance Companies. High rates will in a way prevent building in those areas.
Burden of proof?
