To me it seems like we're just trying to navigate a way to a post-scarcity society with the least amount of backlash/damage.
We could give people money, or we could say "up to so many kilowatt/hours this is free" or "you are entitled to this set-amount of groceries for free". Or to combat prices that inflate for UBI, the government could be reporting what is a reasonable price.
Man I wish I had taken economics. I truly don't know all the ways this could harm us.
