> There are some arguments that those living off of BI would form a unique subset of the population and might effectively be ghettoized at least in terms of colocation as opposed to the more economic/social aspect due to their similar needs/means.

The people living primarily off BI (that is "the poor") would likely continue to be segregated, to a certain degree, both physically and socially from those more well-off. But that's not an effect of BI, that's true of the poor now and basically for all of human history.
