Basic Income in cash, rather than in-kind?

One can conceive of a benefit that would have all other features of a basic income but be provided in kind, for example in the form of a standardised bundle of food, or the use of a plot of land. Or it could be provided in the form of a special currency with restricted uses, for example food stamps or housing grants, or more broadly consumption in the current period only without any possibility of saving it, as in Jacques Duboin’s (1945) «distributive economy». A basic income, instead, is provided in cash, without any restriction as to the nature or timing of the consumption or investment it helps fund. In most variants, it supplements, rather than substitutes, existing in-kind transfers such as free education or basic health insurance.
