The other big question is about the cost side of it. True UBI claims to be able to not be that costly, as it will enable the shut down of all monetary forms of welfare. The resulting unemployment of those employees working welfare related jobs shouldn't even be that concerning, because then the benefit side of UBI would kick in for anyone unemployed. How you study all of that on a small scale is a mystery, as it seems to me that UBI is nearly impossible to bootstrap and will just have to be tried full force at some point with some limited studies as guidance.
