The problem is that that's all speculation. What we see is benign: a well-working society, without explicit examples of fear, poverty, repression or other such woes. The terminology involved may be troubling, but at least nobody is covering up problems with euphemisms. Indeed, for a society in supposed (civil? "international"?) war, the Turkanans appear to be doing remarkably well!
"Government" comes in so many varieties today and yesterday that it's quite inappropriate to credit it with anything, least of all the specific sort of law and order that western democracies today generally value. Yet that specific sort came about because of experimentation. To impose UFP values (whatever those are - c.f. the pronounced lack of consensus within the UFP as discussed earlier) and stomp out the experiment would be tyranny and dictatorship at its worst, especially if it were for purely propagandist reasons (suppression of nonexistent rape gangs etc.). Tellingly, the Maquis were much worse off when persecuted/prosecuted by the UFP for their similarly illegal/contra-UFP-values policies, and nothing good came out of it.

The Maquis weren't "persecuted" because they held values contrary to the UFP. The UFP clashed with them because they threatened to drag the Federation into war with Cardassia. I don't think the UFP would have cared what kind of system or values the Maquis had except for the strategic situation.(which was stupid because the Maquis had supposedly explicitly renounced Federation citizenship but the writers couldn't just drop the storyline)
