It isn't beneficial to the poor suckers whose livelihoods are taken so that the giver has "unconditional" "gifts" to give I'm sure with "no strings attached"
The "poor suckers" in this case are people donating to charity, and the unconditional gifts are, in fact, actually unconditional gifts, specifically set up that way so the effects of them can be studied.
UBI is not a donation. It is forcibly taken at gunpoint (though they will ask nicely many times before pulling out the gun). Also, there can be no "unconditional" giving without "unconditional" taking in a world with finite resources.
The article this comment thread is about is about a study of efficiency of charity methods. It is useful for studying possible effects of UBI-like programs, but it isn't about UBI.
As for UBI specifically...

This already happens all the time. The money for the military and Medicare has to come from somewhere, after all.
