A ton of things in our societies work according to anarchist principles. You also have to remember that a lot of those things are still within the existing capitalist system which exerts its own pressure to the people behind them and regularly corrupts good initiatives by either rewarding/promoting those with sociopathic behaviours within them or by exerting coercive force through threat of homelessness or starvation.

That is to say, nothing of these can be seen as an example of what Anarchism would look like if it wasn't for capitalism. It's all colored by our struggle against the system.
