> But with 99.999%, there is a risk to smooth in practice? How about 99.99999999999999999999999999999999%? Uh, I guess this question might be interesting from an academic perspective, but not a practical one. There's no risk out there which can be predicted with 35 nines of precision, let alone one that people are interested in insuring. And certainly not one in which the overhead of providing services wouldn't inherently dwarf any benefits to both parties.

In other words: There is no practically relevant difference between a prediction ability of 100% and 99.99999999999999999999999999999999%, which is exactly the point I was making: There is is nothing magical about the 100% mark--free will or assuming perfect information is irrelevant to the problem at hand, insurance becomes asymptotically less useful the better risks are modeled and used to set premiums where the premiums cannot work as an incentive to avoid the risks in the first place.
