Well said. I will now try to look from the perspective of a business owner, that has automated everything and doesn't need employees anymore. Let's look at the extreme case, where suddenly (e.g. in 10 years) all business in the world is 100% automated and owned by a handful of people and there is no UBI for the rest. As you rightly pointed out, a kind of revolt is to be expected, which however would be suppressed by the 100% automated police, which would place those poor rebels in a 100% automated jail or just get rid of them in some other 100% automated way. In the end all that's gonna remain is the handful of businessman, who only produce and trade goods between themselves. The amount of goods produced and traded will decrease drastically, which will be detrimental to the government (tax income), which by that time will probably be 100% automated as well. At this point in time, an optimist would inevitably notice that carbon footprint and pollution will also be drastically reduced. However, as business usually goes, those handful of businesses will compete with each other until there is eventually only one business left. There would inevitably be a moment of immense happiness and satisfaction for the one and undisputed winner of this game, but then life will just become boring. The guy will wander around, discuss this with his 100% automated personal assistant, think about it, maybe meditate a bit and would eventually decide look for fun at some other place (e.g. Mars). However, there will still remain some sneaky feeling in the back of his head, asking whether UBI would have actually been a better idea in the first place.
