Then what plans does he have for the disposal of his estate after his death? Almost everyone has legal heirs, even if they're distant family members we don't even know about. All of our tangible assets, including the substantial real estate most of us will have if we live to a ripe old age, passes to them. Most people with no immediate beloved heirs (like my wife and me) prefer to bequeath it to people we've always helped support, household staff, a religious or political cause, or some other charity. In order to make that happen we write wills. The will is evidence that we do not consider ourselves worthless AND that in fact we are not worthless economically. I have life insurance to take care of my wife in case I die in the few remaining years I have to work before retirement. The value is roughly equal to my remaining lifetime earning power. But if by some tragedy we die together, the proceeds of the life insurance goes into our estate and will be distributed along with our houses and other assets. The local animal rescue organization and the Central Asia Project will get quite a windfall, in part because my life has economic value. Younger people who have no family generally don't bother buying life insurance, but it's not because they consider their lives as having no value. Quite the contrary: by saving the life insurance premium and adding it to their disposable income, they're spending that value now instead of letting it accrue to their estate. Lots of people who do have families nonetheless fail to buy life insurance. Basically, they're gambling. Most forms of gambling are not played in casinos and are therefore legal.
