The alternative to UBI + all jobs automated away is just all jobs automated away. I don't see how UBI is the problem here.
This is a logical fallacy. It can be claimed that any human right can make the population complacent: 5 days work week, public healthcare and so on and there is no evidence to prove it's true.
On the contrary, it's well known that people with free time can become socially and politically engaged, while people working 2 jobs have no time for it.
