Sometimes getting rid of the debt means that you can begin to restart. Of course, it won't help you afford a non-free checking account nor pay bills, but it can lead to marginally better jobs and nicer housing for the price. Sometimes that price is worth it because it brings a bit more piece of mind - no more phone calls and letters. A good number of unbanked aren't even as poor as you might expect - things have happened and they can't get to a point to restart.
And some people, no. No they wouldn't care. Like most people, it depends on life situation.
