Even in that case there's a tradeoff, if that stack needs to be large you can maintain it on the heap. Now you can do that to some extent with either a recursive implementation or not of course, but it's still a matter of deciding which is the better approach. It's not simply the case that "you can always just use recursion and it'll be totally fine mostly".
