As always, I feel compelled to point out that Turkana IV was never said to have been a member of the Federation - they “severed relations” with the Federation, but that doesn’t necessarily mean they were a member (in fact, I think it strongly suggests that they were not, as that’s a very clunky way to refer to secession).
That's a reasonable objection to raise but I'd counter with the point that it seems unlikely that a human colony could be established except under the auspices of the Federation, or at least United Earth.
