“Aside from the broad categories of minority, insanity, and deprivation of civil rights, the California statutes occasionally preclude certain persons from contracting in specified circumstances. For example, by statute, the public enemy may not be insured. In a sense, such prohibitions may be viewed as depriving the designated persons of the capacity to enter into the proscribed contract.”
