That isn't entirely true. How much is it worth to upgrade from a "once every 500 years" system to a "once every 5000 years" system? If it's more than the expected damages...

Well if my country floods its all over, considering we're under sea level the water may never leave.
And I can imagine Japan doesn't want to risk Tokio.
When you start talking truly cataclysmic events, the value of the physical infrastructure at risk will be dwarfed by the human lives. In 2016, the assessed value of all real estate in Manhattan crossed the $1 trillion threshold (which of course leaves out the bridges, the subways, the personal property...) At a value of $9.1 million / life, there are $77.7 trillion worth of humans in New York City.
If there's a natural disaster which would wipe out the population of New York once every 5000 years, we should be willing to spend $15 billion per year to prevent it.
