I understand what you mean and I agree that in those cases GMaps is more useful. But then, if no one adds anything OSM database will always be empty. So, if you don’t find something, use GMaps, that’s fine. But then, what you were looking for should be added to OSM (after real-life checks, since GMaps cannot be used as a source) to help future users.
