Do you feel the same way about foodstamps? This isn't an argument against UBI, it's an argument against any kind of government provided assistance at all.
It's purely speculative FUD. It would be terrible if they did that, so make sure they don't. But it's a completely independent problem.
If that's the case, then I would personally feel the same way!
Not to make any argument for the feasibility of the idea, of course.
If people truly need to rely on the government for food, it would be absurdly inhumane of a society to let them starve.
Simultaneously, promoting reliance on the government and attempting to make that reliance universal has the potential to take away our freedoms.
Food stamps is an acceptable principle to Americans because it's meant to be temporary and need-based, and if you remove those two characteristics, it isn't just a reductio ad absurdum argument of taking the same concept further; it's entirely different.
