Rentier classes clearly do live without work, it's largely a question of how large of a population can live without working. If the fundamental tension in Marxist theory is real, then one could argue that a UBI is insurance against a populist uprising demanding a living wage. Religion might have been the opiate of the masses in the past, but if price stability with a dole is feasible then I can guarantee you there's going to be a significant share of the population who wants to do nothing but sit around and engage in idle socializing, sports, or art. Provided that there's also still a differential for working, then people will still chase after prestige but not be threatened by destitution if they choose a sub-optimal career path.
