The idea that there is nothing morally wrong with not helping another person if there is no risk of hurting you and they'll be hurt or even die if you don't? That's pretty offensive to me. Also, "enlightened selfishness" isn't a thing. It is just selfishness. And it doesn't work economically. When companies aren't regulated, they do whatever they can to get the most profit for themselves and screw over everyone else in the process. Objectivism, IMHO, is bad both in theory and in practice.
