I imagine to appease anyone with doubt to the benefits of basic income some sort of "basic work credits" type system would need to be in place for anyone without a normal job to contribute something noteworthy back to society.
The matter of what is acceptable as "basic work" may already be in place as court ordered community services, peace corps, or local public works projects. Maybe even a new variation of non-profit organization [1] that has specific structural rules for "basic work" credits?
