A lot of life insurance is term insurance. So the bet is "will you die during the years that your policy is in force?" Whole life is much, much more expensive.
Could you then have the same kind of structures for flood insurance policies? I had to pay every year to renew my renter's insurance policy, it only covered losses during the course of that year, and the insurance carrier had discretion to adjust the premiums or not to renew it.
In the US, flood insurance is provided by the government. And the premiums still jump insanely sometimes.
It gets handled this way for the same reason our government provides welfare et al: it makes no sense as a business, but the cost to the nation to do nothing is a bigger problem.
There is some private flood insurance these days, but I don't know who offers it, in what locations, what the premiums are, and what kinds of exclusions there are. Since it's a new thing, I think the claim that it'll be vastly better than NFIP is invisible hand waving. Nevertheless...

I think the bigger issue is that there is an inherent incompatibility between free markets (or strict laissez faire, non-intervention of any kind) and democracy. Of course people, in the millions, are going to say "help us" and direct it at their various layers of government, and punish those who don't at the election booth.
Therefore it stands to reason in major floods like this, that everyone is going to get some kind of relief even if they didn't have flood insurance. What I'm not sure of is whether the insured get 100% payouts and those not insured get partial payouts? What's the incentive to have flood insurance, except in smaller, localized, 50 or 100 year floods?
This is asset destruction and the only way to properly handle it is through savings. So it's either made compulsory or you do end up with something of a free loader problem. Whether that free loader problem is a real problem, I don't know.
How could term insurance for homes be possible? Homes are (despite some fluctuations) relatively good stores of value that you want to pass on to later generations. Comparatively, once a typical human retires from working, he isn't producing much of insurable value (and presumably, his offspring are capable of achieving financial independence).
Homeowners insurance is all term insurance, the contract only covers a short period of time. At the end of the contract, the policy holder doesn't have anything.
