If by 'anarchy' you mean community-based living and direct democracy then I would say yes, absolutely.
While I agree with you in a sense, I also believe that this is really a pipe-dream. People been fuckin', fightin', gettin' mad, gettin' sad and getting happy in no particular order since the dawn of man. Humans are in no way altruistic, and IMO most people who believe that they can be or that they are - aren't being fully honest with themselves.
I grew up on a commune in Northern California until I was 8. We had a little set-up akin to the one you describe. Most of the money was made off of the outdoor cannabis harvest every fall and my parents along with the other families, were freaky swinging hippies. They met and discussed things with how the land was to be run, we ate communal meals and lived off the land for the most part and my childhood was pretty rad aside from the ants.... so many ants...
While this sounds cool and dandy, it has the same pitfalls as any other society and group of people trying to satisfy the veritable desideratum of the many. People get greedy, people get selfish and people, most of the time IME, look out for themselves and their families over anyone else. I know this is going to spark an out-pour of bleeding heart 'you're just not enlightened/optimistic enough' or 'well they had the wrong reasons/mentality' crap, but until you have seen/experienced a true outsider communal society in the middle of nowhere operate, you can't say shit about if it works better than what you currently live in or that it would make anyone less depressed. It's a pipe dream to think that the problems that have plagued society since day one would just disappear in a 'community based direct-democracy' and it's a cop out to take action to better life in the current system, however flawed.
(I know this went off about more than just depression, I just had to rant a little)
