I'd even argue that "relative" poverty at least (i.e. once one escapes actual, severe deprivation, which is mostly a factor in underdeveloped countries but not entirely unknown in the West, either) is all about the "being alone" factor. The best "anti-poverty" policy, once material abundance is achieved (and a UBI can help with that) is to promote social inclusion and to strenghten institutions that provide social capital.

Conservatives understand this very well, BTW; strong social capital is key to the conservative worldview, whereas a "liberal" is often more inclined to see the world in terms of material relations of production and an inherently-unstable balance of power, and even the very notion of social atomization might be entirely foreign to them.
