It's more a way to drive a point home. Taleb has been shouting this point for more then a decade. A portfolio without insurance is no portfolio. His arguing is that institutions that are to big too fail hardly ever insure themselves in this way, using optimistic lineair growth models without hedging themselves against extreme and unpredictable risk. And then when they go bankrupt they present the bill to the tax payer.

It seems necessary to make a point here since these models haven't changed for decades even though they have clearly failed many times.
