The only - [ugh let's not be profane here man c'mon] - things that anarchy can accomplish are short-term; you can't possibly hope to change anything using such methods, at least not for the better! Establishing some sort of order is necessary for everyone to benefit; there are those who can't thrive under pure anarchic conditions, through no fault of their own - that's neither fair nor just, nor will it benefit anyone in the end. There's a reason anarchic societies fail to exist nowadays!
