>But I can't see why she thinks that.
The answer, which is this clearly the author's position, is self-evident if one moves from assessing the situation from the profit-motive lens: a stop to the practice of predatory lending.
Earlier, the argument was "Isn't this consistent with poor people needing loans": they don't need loans, they need a livable wage (which I know is a whole different story so won't go into that), but since they can't don't have a livable wage, they need financial support to tide them from non-livable paycheck to non-livable paycheck, that does not cost an arm or a leg, as they make sacrificial decisions as to what to make do with/without.
The argument that people are being given more choice is a lie - there is literally no choice here.
The lending is literary predatory as it is i) from a lender of last resort and ii) comes with interest and fees that would be intolerable to anyone with options.
Non-predatory lending is just one part of what the writer describes as ".. do the good loans without doing the bad loans."
