Hayek on why a guaranteed minimum income promotes individual freedom by weakening dependence on tribalist ethnic/religious/etc. groups:

But the danger from foreign enemies (or possibly internal insurrection) is not the only danger to all members of society which can be effectively dealt with only by an organization with compulsory powers. [...] The assurance of a certain minimum income for everyone, or a sort of floor below which nobody need fall even when he is unable to provide for himself, appears not only to be a wholly legitimate protection against a risk common to all, but a necessary part of the Great Society in which the individual no longer has specific claims on the members of the particular small group into which he was born.
