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.

I would assume that earthquake insurance in japan is a reasonable model for "world insurance".

It looks like it's a reinsurance program:

So, I think the answer is "no".

Japan is probably not a good comparison for home insurance because houses in Japan typically only have a 20 to 30 year lifespan. After that they are usually torn down and a new house is built.

Why would anyone tear down a 20 year old house? Where I live the houses are 80-100 years old and they’re better built and nicer to live in than most newer homes.

The traditional materials used in Japanese construction of everyday homes aren't really in the "built to last" category: https://www.youtube.com/watch?v=i1DP5xpM3Y8 . In some cases, trying to make a house that was resistant to floods, fires and earthquakes at the same time would have been prohibitively expensive. I'm sure that led to forming habits that have continued into more modern eras of building styles where it's less required.

They're also smaller, which makes construction costs cheaper which means people are more likely to make dramatic changes when fashion changes. And then there's more of a culture of prefab house building rather than extensions etc. Planning is also a lot more liberal which allows the rebuilt house to be more different and also reduces the cost of the process.

I think even in Europe some of the older houses are houses of theseus though. The exterior shell is the same, but there's plenty of buildings in the local city centre that were tenements, then small business offices, then apartments, with significant remodeling that occurred. Or the house I used to live in was built in the 1880s, extended in the 1950s and significantly modernised in the 2000s. Each time there would have involved largely gutting the interior and rebuilding.
