Apple is #4 in laptop sales. Lenovo, Dell and HP each have at least as much volume. Apple also has higher margins than those companies, implying that any cost savings they make on other components aren't making it into the price anyway.
It's probably just that it costs a little more to do it and most customers wouldn't pay a premium to have it.

True but they divide their sales among several models. Gaming models, 2-in-1s, 13" to 17" and so on. Apple not only has fewer models they often keep the same case design between generations which also benefits economies of scale.
