I think the UBI will work as a transition model towards a resource based economy where you have no government and where money does not exist and automation has grown to a much higher level where access to things are freely given to everyone. But in order to get there the value system needs to change accordingly from consumerism to sustainability where the environmental effect is taken into consideration. Problem is that the money system of today has no incentive of sustainability and environmental effects because money is driven by profits.
I fully support the UBI but we need to change the current economic model as well because otherwise we just generate even more debt which will just end up with a collapse that hurts everyone. I do not support taxation as being the source of the UBI because I do not believe in theft but I am also well aware that we will not get rid of the notion of government anytime soon. We could maybe close current welfare programs that are working on finding out who should get welfare and not and use that kind of money to fund the UBI.
Here is the answer from the TVP about UBI being a transition to a RBE, maybe it will give you another perspective on this topic of UBI.

what will be the results of self-replicating 3D printers which can print a MUCH broader feedstock? Right now the cheapest and most common is plastic. High Dollar models can print metal. There are even some that are biological. Suppose a printer is developed (not if...but when) that can do all that...AND print more printers? Suppose that a filter is developed (not if, but when) that can separate the 'impurities' (one man's trash is another man's treasure) from water, air (landfills?) and use them for feedstock? Not only using solar power (or thorium?) but printing it's own solar panels?
what happens then?
I have no idea what will happen then but I am well aware of the development of the 3D printer and how it can move the production into peoples homes instead of having it externalized. I think it's possible that something like the replicator in Star Trek can be something that we will see in the future and that itself could transform the entire world from a scarcity based system to a system of abundance.
