If you can hard link a directory, what does "cd .." mean? (There are multiple answers to this, including the account's one: "what do you _want_ it to mean?") If you can hard link a directory, you can make loops in the filesystem, making a directory tree seem infinitely deep. Finally, please nominate specific tasks that can be accomplished with directory hard links that cannot be accomplish with other mechanisms. (Clue: chroot and "mount --bind" et al.)
