That neither addresses nor counters his point. You could hardly expect someone to make a connection to something they've never experienced... That's a rather odd thing to expect.
You can make the same argument for Avatar. Avatar stole a lot of its elements and tone from other movies and stories like Fern Gully or Pocahontas (and probably others I can't remember or don't even know about). But just because someone hasn't seen those movies, doesn't mean the connections aren't there. As many people have complained, the movie feels like a blander version of the stories it ripped off.
Lone Ranger did indeed feel like a Pirates knock off during many parts of it. One of the villains (Butch Cavendish) is very reminiscent of Captain Barbossa (especially in looks), though infinitely more bland and predictable in his villainy (Barbossa you could actually almost sympathize with as well as hate him even in the first Pirates, and he got even more interesting as the movies went on, awesome actor playing him too). Tonto just acts like a more quiet and calm Jack Sparrow throughout, but often does things directly out of Jack Sparrow's repertoire of stunts and silliness (never bought Depp's performance in this one even though i'm a big Jack Sparrow fan and generally a huge fan of Depp in other roles). It honestly just felt like Jack Sparrow dressed up as an Indian and was making fun of the situation he was in most of the time. And the Lone Ranger himself played second fiddle to Tonto throughout, feeling very much like a retread of Will Turner (including copying a lot of his goofball moments).
That's not why I disliked the movie myself. I can forgive movies being derivative as long as they do something good with the material they're taking from. But that wasn't the case throughout most of the movie. I felt Lone Ranger had a lot of bland and pointless filler that just dragged the movie throughout its too-long runtime (along with often uninteresting dialog). It could get very boring in parts. Certainly had some highlights, particularly the action scene at the end with the train, loved that. I don't think it deserves the beating it's getting on many sites. Particularly since there are many far worse movies that have gotten better reviews and box office sales. But I wouldn't call it a good movie by any means.
