There are, to change the domain somewhat, other lifelong illnesses, which arent mental disorders. TDR-TB -- totally drug resistant tuberculosis -- is one of these. Worse, unlike schizophrenia, it's contagious.
And the only viable public health responses are either a total quarantine of infected populations, or killing them.
If you reject the latter, and i hope that you do, you're left with a situation not much different from that posed by schizophrenia: the prospect of institutionalisation, but under terms and conditions in which the afflicted will prefer and seek out that option. Or at the very least not resist it.
I'll also note that lifelong imprisonment is not necessarily the only option, you're appealing to the extreme here. Though sometimes, yes, that _is_ what society must do.
