In Atheism and Theism, alike, it is easy to find people who live by strong sense of obligation to do good and to avoid doing wrong. It is, unfortunately, also easy to find people in both groups who don't. So, from that standpoint, I don't believe that Atheists are any more susceptible to anarchy than any other group.
That said, I do think there is a valid argument for the what SamBee has said...

... God is a useful myth (if not real) of course, which helps humanity function in a more civilized manner. Many, but not all, who believe in God, have the idea that their good and bad will be repaid.
If we were all altruistic and bound by our inner drive to act ethically, I don't think there would be so much need for laws and law enforcement. I have jury duty this week, which is an indicator that crime is still alive and well. If people had a belief that they could "get away with it", I have no doubt that there would be even more crime, but as it is, punishment looms large enough to keep people from doing what they already know to be wrong. God simply offers another layer to the equation: it might be a lot later, but his judgment is "something you can't avoid". I suspect hope for reward, fear of punishment from God works especially well among people with the long-view always in mind. The same people who save diligently for retirement are the people most likely to have a slightly altered trajectory if they have a belief in God.
So, while I vehemently reject the idea that no morality can exist among Atheists, I do believe (and I don't think I'm betraying my fellow Atheists) that Atheists have less motivation than Theists to be good on an every-day basis. That lower motivation, means that for Atheists to act in good ways requires more work and personal commitment - a sort of self-imposed discipline. Put another way, if I lost my wallet, would I rather have it found by an average Christian or an average Atheist? Both know it would be right to look me up and return it with all the cash inside. There are some Christians and some Atheists who would do exactly that. There are some Christians and some Atheists who would take out the cash and throw the rest in the garbage. But if I'm playing percentages, I'd probably rather have it found by an average Christian than an average Atheist.
Note, though, that I also caveat this by saying that self-assurance in a higher power can and does have an effect of sometimes allowing people to jump out of the morality lane entirely, in ways an Atheist would be much less likely to do, with the notion that God approves for a higher purpose (killing Laban, polygamy, Danites, MMM, to name a few).
