I don't know about your statement that all DSM Dx result from politics as being totally true, especially the Axis I's. If they ever declassifiy the various schizophrenias, we are in big trouble!!! Most of those people are seriously mentally ill!!!....AND DANGEROUS.
If we find individuals dangerous, as in guilty of violent crime, "crimes against property" or threat of same (towards others), then prosecute them.
I see no need to think of "mental illness" as anything other than a metaphor.
I'd remove psychiatrists as expert witnesses in court proceedings.
I view psychiatrists as "metaphorical doctors". Like viewing an editor as a "literary doctor".
