<prompt> Human: For car and health. I exclude home because homes are typically scaled to the worth of the owner. so I figure a billionaire would have his hundred million dollar house insured.  <response>: I cant think of any asset level at which buying at least auto liability insurance and high-deductible health insurance would not make sense. Both of those types of insurance cover unforeseeable and more-or-less unpreventable scenarios that could potentially cost a person hundreds of thousands of dollars, and if you are at the financial level where you could handle that kind of a loss without a problem, then the premiums on an insurance policy wouldnt even amount to pocket change, relatively speaking, so there is no real reason not to have the insurance. Self-funded insurance is really more of a useful tool for businesses and corporations, whose insurance premiums could otherwise be a fairly significant cost.
