This is by design. Marking a file in .gitignore tells git that the content is not precious and can be removed if need be. For most ignored files, this is what you want (e.g., you mark "*.o" as ignored because it is generated; you do not want to add it, and you can always make it again).
The less common case is a file that is precious and needs to live inside your repository directory, but which you do not want to add (e.g., a config file that affects your project, but should not ever be committed). People have occasionally asked for a .gitignore-like mechanism to mark such files as "precious but do not add". However, nobody has actually implemented anything.
