I agree. for me, the real problem with Rand's approach and with any system that does not allow for an objective basis for good and bad, is that eventually pure selfishness inexorably creeps in. It becomes very subjective (real irony in the name "objectivism") and devolves into the only real values are my own. It is closer to Nietszche than Christianity and as Nietszche saw clearly, power is all that sustains and enforces self-driven systems. If you have the power, you rule. And if you don't have the power, you are the ruled.
