If Yoda or Ben wanted to keep Luke hidden away from Darth Vader, why would he go by the name Luke Skywalker on Tatooine? Wouldn't the Skywalker name be well known there, especially since Anakin Skywalker becomes Darth Vader? Wouldn't it be easier to Luke under the name Luke Lars? I have always wondered why no one made the connection between Luke and Anakin. Any thoughts?
