This is why the "Universal" aspect of it is so important. It's ridiculously easy for people to vote for defunding services that "other" people benefit from, and politicians can always whip up support by scapegoating some minority group as the root of all of our problems. But if the benefit is shared by everyone then it becomes near political suicide to suggest cuts to it. How many politicians successfully can campaign to get rid of social security or medicaid? Those are programs shared with a significant percent, but not even a majority, and as such it's really hard to successfully push for cuts to such systems. With a total universal application of basic income it would be political suicide to push for cuts, everyone's life would be planned and organized already around such a program. Look at how hard it is for universal healthcare systems to be cut in nations that have such a benefit.
