It does seem clairvoyance would negate the need for insurance, but that prompts another question: why do you think a clairvoyant person or machine is possible in any way? Also, if an insurance company had perfect knowledge of future claims by being clairvoyant, they could charge a suitable risk premium to write policies where they wouldn’t lose any money, since they would also know how many policies they would be writing.
