The 'unconditional' part is only important in the beginning. Once the subject qualifies (begins receiving the annuity) then the criterion is irrelevant to studying their behavior while receiving the benefit.
For the person receiving them, those things listed offer the same benefits as BI - money regularly received no matter how you behave. To determine what effect that has on people, then we need simply record those results to get a large data set.
To fund even a tiny study (a dozen people?) for a tiny amount of time (5 years?) would cost an exorbitant amount. Its kind of silly to even talk about. Especially when we have data sets of millions of people in almost the same circumstances.
I read this proposal as absurd. Its typical of Silicon Valley to imagine getting results from a tiny study (focus groups etc) that are worth anything.
