For the individual, maybe. At a societal level, at least some people are required to live in rural areas, so we can have the raw materials society requires.

The fact that disability isn't a choice means that disabled people can't become undisabled, and abled people probably shouldn't make a choice to become permanently disabled.

Because rural/urban living is a choice, this means people can come in and out in response to supply and demand via the price mechanism. If rural areas are viewed as undesirable, rural wages will rise until it justifies people being there.
