It's an interesting topic. So let's say many people get laid off as automation takes over. If we have UBI that covers mostly bare necessities (as an example), shouldn't supply and demand stay basically the same? Or demand even lowers if people can't afford what they previously did.
If people have more money (or population grows) so that demand grows while supply stays the same, prices will rise and find a new equilibrium where people can again afford less and therefore buy less.
I'm not sure if it's an option to just leave most of the population to starve either so what's the alternative to some kind of social security or UBI? Long ago, a factory called "nature" used to provide relatively more of our needs, but that's not feasible today. But this quickly gets philosophical and political, of course.
In any case, finite resources are finite regardless if we have UBI or not.
