That money gets spent and comes back as tax revenue. If you think UBI is expensive, wait until you find out how expensive it will be to have a hundred million unemployed (as a result of automation for one). You give people money, they spend it on goods created by robots which are taxed, earning money to hand out to everyone as a dividend for being an owner in the national enterprise.
