"In addition, higher taxes are discouraging to innovation and businesses, which may be prompted to move elsewhere, outside a UBI zone." - unsupported assertion.

"In addition, higher taxes are discouraging to innovation and businesses, which may be prompted to move elsewhere, outside a UBI zone." - unsupported assertion. "if a UBI payment were to be small enough to be financed by existing tax rates, it could lead to mass starvation and poverty" - really? "Few supporters of basic income have been able to prove it would be less costly for states to implement than existing welfare offerings" - the point is not that it is less costly - UBI is a replacement, so the cost would be equal or maybe more. If less, that's a bonus "What’s more, a basic income could have a detrimental impact on inflation." - economic illiteracy. "Conversely, a universal basic income free of sanctions and restrictions would push wages upwards, and have an inflationary effect." - any inflationary impact would be one-time. Also, what you call wage inflation, others would call deacreasing inequality. US wages have remained static in real-terms for decades. "An unconditional basic income discourages career progression and innovation, could potentially have detrimental economic effects" - pure conjecture, or just plain wrong. Innovation happens because it is driven by intellectual curiosity and passion - by not having to worry about financial security, people are freer to innovate. Up till a few centuries ago, only the rich could afford to be scientists, vide Newton. This is not a serious exploration of UBI - its a cheap hatchet job.
