On the contrary, the outlandish claim seems to be that anything could be impossible to insure.

Insure profitably? Sure. At some point, the cost of the premium exceeds the cost of the thing being insured, making it pointless to insure.

Some people describe this scenario as something being "impossible to insure", but it's not meant in the literal sense. In fact I would argue that there is no insurance company that would decline to insure a $100 million cargo through a combat zone, if the premium offered was $150 million.

So no actual source?

The article from flexport states that insurance rates through there are 3.5x of what they were in the beginning of december

Do you have a source for your extraordinary claim that such insurance cannot be bought? Surely such a divergence from the status quo would be written somewhere more official than a social media comment.

War risk insurance absolutely exists.

The original claim was about 'sailing in a conflict zone', a.k.a. getting fire insurance for a house that is already on fire.

The original claim is "You cant get insurance for sailing in a conflict zone." Which we have clearly shown is false by showing current insurance rates for sailing in this conflict zone.
