Rojava could exist here, that's for sure, if you somehow teleported it over it wouldn't regress politically -- what would be the reason for people to allow that?
Heck they probably could even join the union: You need to be a democracy, and a market economy. Democracy goes without saying, and distributing food and decommodify what they can doesn't mean that they aren't also a market economy. They're just taking the "social" in "social market economy" more seriously than our socdems over here. OTOH they probably wouldn't want to but join EFTA instead.
As to "not a good example": It's true that liberal democracies limit revolutionary zeal that's why being an Anarchist in the west is kinda... erm. I don't want to swear or jinx the nice stop-gap we have going on here. OTOH you should acknowledge that if they manage to do it between a rock and a hard place, the system itself is plenty stable enough to work under better conditions.
