It's not clear from this how large a guaranteed income he supported.
If he was thinking that the total amount paid out by the state would remain unchanged as existing welfare programs were replaced with a universal guaranteed income, then he was imagining an income so small as to be of very little use to anyone.
If he was imagining a universal guaranteed income large enough to fully pay for everyone's basic needs, then I wonder how much of the extra expense he imagined would be paid out of his own pocket.
