Or imagine a woman who has children out of wedlock, causing financial distress. Obviously, if she's not institutionalized she'll continue to have children out of wedlock, which will cause her condition to worsen.

And only a mentally ill person would have children out of wedlock, right?

And before you say that that's unrealistic... I'm pretty sure that that exact logic was used to institutionalize people in the US back in the 20s and 30s.
