Owen and Anakin should have had a disagreement over him joining the clone wars and not staying to be a moisture farmer. Of course, in that event Anakin would have to be much older closer to Luke’s age in Star Wars. Little orphan Anni would be erased.
It just shows you how bad a liar Ben was, he lied about Yoda being his master and Darth Vader killing Anakin. He lied about Anakin’s motivation to become a Jedi, he said Anakin wanted Luke to have his lightsaber when he was old enough.
It is funny of course it’s just George making stuff up on the fly and retconning, never with a mind for what he wrote previously.
