The part where I dont care when they started wanting it. People always want their freedom from something. Doesnt mean Russia gets to invade.
They needed to do something about it and establish themselves as legitimate before they can invite other people over. The only reason Transnstria has any legitimacy is the Russian troops there. That's putting the cart before the horse. And that's the same Russia that doesnt recognize them as their own country, a point you continue to avoid.
I would look at somewhere like Somililand as somewhere I would be fine with the Russians, or others, working in. Largely stable, largely independent with separate government systems and infrastructure, not recognized on the world stage
