My preferred argument in favor is that depression can render government form-filled disability bureaucracy into an unnavigable hellscape and since it's one of the most common disabilities, a lot of human misery could be spared by making a living income automatically accessible.

You don't honestly think that those of us who have doubts about UBI are actually cackling and rubbing our hands together gleefully over all the human misery we're causing by denying living income to the miserable, do you? Of course that would be nice - and I do believe that humanity will eventually get to that point, but we're not there yet. We'll have flying, self-driving cars long before we have the level of automation we need to let everybody kick back and pursue whatever intellectual interests they find.
