Ranger, I disagree with the last possibility in the above comment because of the conversation the Strawhats had with Caesar on the Sunny. Chopper was praising his ability to create artificial zoan fruits then that was dismissed because he just copied Vegapunk's research from years ago. Vegapunk > Caesar so the Navy don't need to learn anything from him
