I was taken political prisoner three times in the Broadlawns facility ran by Polk County Iowa - currently helping Federal Medicaid claw back the fraudulent $20k hospital bill. Lynchpins of the rampant political corruption is nepotism between Chief Justice Susan Larson Christensen/ brother 4th District Chief Judge Jeff Larson and Hon Mary Tabor/brother Chief Deputy Attorney General Eric Tabor.
What you speak of does exist, it's Medicaid - the issue is only in states like Iowa do you have such due process free statutes like Iowa Code 125/229 that magistrates can lock you up without solid evidence that the person is a true threat to themselves or others.
I can't say that in-patient mental health care (for non-wealthy) is available nowhere in the US. But it is scarce enough that you may have the only example.
I am excluding 72hour-hold facilities because they are more like an extended Dr.s visit, than any sort of rehabilitation.

I saw several women that were domestic abuse victims - their family labeled them as crazy because Iowa doesn't really have any emergency shelters to speak of.
