The article that you linked was well-thought and well-written. I liked the more bottom-up approach to the issues and that Mr Sarris at least offered kernels of alternatives.
Ignoring for a moment that the decision-making ability of the US legislature is all but broken, I worry that the sheer complexity of the issues surrounding UBI would make adoption – or even learned consideration – impossible.
And, as you and Sarris mention, the relationship between UBI and healthcare and housing (rents) is a whole other can of complexity.
