Stirner came to this conclusion first and the responses he got were mostly "yeah, but it would really suck if everybody thought this way." It's akin to a prisoner's dilemma on a societal scale. Basically sociopaths have a competitive advantage over everyone else, but if everyone is a sociopath and there are no shmucks left in the world, then everyone is worse off. So the metagame is to reinject morality, pretend to be altruistic, convince enough people to go along with it, while secretly being a sociopath yourself.
