It’s just that maximizing your preferences (having children, going to starbucks, whatever) is often at odds with maximizing the subset of your preferences which you identify under the category “moral”. This example only seems single-minded because moral preferences are just a small subset of all your preferences.
If you strive to maximize all of your preferences (which is what you are striving for anyhow, in theory) rather than a limited subset called “morality”, you’ll see that every action which you would prefer to take is in fact the action which will best maximize your preference function.
