> I think the idea is that a UBI would increase the cost of labor

Different UBI proponents (which come from across the left-right spectrum) have different ideas, but none of them that I've heard from has favored UBI for the purpose of increasing the cost of labor generally. Especially on the right, but also usually on the left as well, reducing the disincentive to work inherent in means-tested social benefit programs, and avoiding the same problems that minimum wages seek to address while not limiting the minimum economic value a job can produce and be worth offering are frequently cited motivations.

But is this still an effect which needs to be considered? I can only see it increasing the cost of labor if people are only willing to work for the luxuries they desire and no longer for the basic living expenses.

By what other means would it encourage automation at all? Or is that not an intention or benefit at all?

Its not really intended to encourage automation, from what I've seen from most proponents; the relation to automation is that automation is happening now, and expected to continue with or without UBI. Proponents of UBI (particularly on the left) see this trend as a significant contributor to declining real wages for most workers, with the gains from the growth of the economy going to a relatively narrow set of elite workers and, even moreso, a much narrower set of capitalists. They see UBI as a means of compensating for the harm most workers experience in this, redistributing some of the net gain so that the aggregate gain that these changes contribute to benefits everyone. Productivity increases don't need to be encouraged, they inherently produce their own reward.
