Yes.
Simple question you need to ask. If we put this program in place for 10 years, then cut it off. What will the proponents of the system say then? They will argue that people are entirely dependent on it for their daily lives.
I can ask this question of the existing welfare state in South Africa, which is already unaffordable. Lets say we get rid of free electricity, because there is no spare electricity in South Africa. What will the proponents of free electricity say about that? They will say that the people who use it are entirely dependant on it, and that getting rid of it will ruin their lives.
The only, and I mean absolutely only way you can do UBI is to privatise pretty much every function of the state other than the military and judiciary. Police, fire services, water, roads, healthcare everything, and rather hand that money over to people to spend it in the way they see fit.
