So, in practice, I imagine there would be lots of offices and agencies, services and interdependent liaison offices and agencies along with the requisite inspector general offices and agencies and the necessary committees, subcommittees, and working groups that would have to be created.
In the land of government bureaucracy, the rapidly increasing fixed-pie of current and (hopefully) future taxpayer revenue gets divided up into more and more slices every day.
However - I've always been puzzled by how each person in the US doesn't have a public, singularly identifying number assigned. Doesn't that make even an 'universal' basic income hard to define? How do you guarantee that every person gets one, and only one, BI check every month? How do you find out who is dead and should stop getting one...?
From what I know, SSN are used for stuff like that, but there's all this weird stuff about it (althoug I admit my knowledge of it comes from a half forgotten CGP Grey video, and that the impression that stuck)

Also this paragraph from the linked article suggests that the 0.7% figure does not include means testing:
Indeed, universal participation and the absence of means-testing make Social Security very efficient to administer. Administrative costs amount to only 0.7 percent of annual benefits, far below the percentages for private retirement annuities. Means-testing Social Security would impose significant reporting and processing burdens on both recipients and administrators, undercutting many of those advantages while yielding little savings.
