You are overlooking the deflationary effect of technology. Jeff Booth, author of “The Price of Tomorrow,” describes this in very intriguing detail and suggests that we will either have UBI or disruptive revolution.

In your example of most UBI going to greedy landlords, you fail to consider the increasing ability of competitors to the landlord to provide lower rent due to innovative low-cost building techniques. If Jeff Booth’s arguments have any merit, a low-energy, deflationary, low-growth economy will re-value work so that a massage therapist that in the past that needed UBI won’t need it any longer since she will be earning a much higher income relative to other services that can be provided cheaply because of technology.
