UBI to me begs the questions: "where does this money come from? Who dispenses it?"
Answer: the government from tax revenues / nationalized industry the products of which it sells (mostly outside its border to a non UBI state or perhaps locally if it's just more than break-even.
Basically, comes down to a government / state controlling everything you do - and the gradual erosion of personal choices and liberties as they're seen to be at a higher cost, etc.
No, thank you - I refuse to live in such a dystopian world.
