I think a major feature of a UBI/NIT would be to make it entirely location independent. There are tons of areas in our country that are economically depressed, largely due to a lack of jobs. These areas typically have low cost of living, so someone on UBI would be able to live a lot more comfortably there than they would in a high cost job center.

And this in turn would provide some monetary inflows into those areas that could help revitalize them. A lot of these areas are occupied by seniors living off of social security. An influx of younger folks with UBI checks would help balance things a bit better.
