Skywalker--the Smiths of a Galaxy Far, Far Away?

Skywalker. Smith. Skywalker. Smith. One name is dynamic and seems to usher in thoughts of lightsabers and stunning piloting skills and deathstars, dismemberment, and Tatooine. The other? Not much. A plain name, an average, common name that we use in cheap motels. But are they that different? Maybe, maybe not. After all, "Skywalker" may very well have been the "Smith" of the Star Wars galaxy. It must have been. How else can you explain it--explain the galaxy sized hole in the plot of the Star Wars saga that involves the anonymity of Luke? As I have said previously, I absolutely love and adore Star Wars and am a Star Wars Geek. But, but, but...the Skywalker thing. It bothers me. I know that the apologists will dutifully explain to me, as if I am a complete idiot unversed in Basic, that Tatooine is a desolate desert outpost, a "barren wasteland," and that on Tatooine, they don't get the daily paper.
This explains why Anakin Skywalker, the most spectacular and famous Jedi knight in the galaxy is apparently unknown to the fine citizens (actually, they're a hive of scum and villainy, at least in certain parts). It's why nobody on fair Tatooine, not Watto, not Ani's childhood friends, and not any of the thousands of spectators who watched Little Ani become the first human to win--not just compete in--but win a pod race, says, "Hey! Remember that little bugger who won the pod race, his name was Anakin Skywalker and now there's this insanely powerful Jedi named Anakin Skywalker...I wonder if it's the same person?!"
And the plot hole widens. After Ani blows up the droid command ship and wins the Battle of Naboo for the Republic, no one on Tatooine, which we have learned is a desolate desert outpost, says, "Hey! That kid sure is something...first the pod race and then he wins a battle all by himself! Wow. That's a name I'll have to remember!" It's the first major battle in a thousand years and you're telling me no one catches the name of the kid? You're telling me that Tatooine (a desolate desert outpost...) doesn't hear the news? It's that remote? And yet it's in five of the six movies? Umm...okay. Coruscant, the capitol of the Republic is in only three of the six movies (I'm not counting the window dressing victory shots that were edited into the Return of Jedi). But Tatooine is in five of them. Umm...okay.
And the plot hole widens. Luke has friends going to the "academy" and they know about the rebelliion on far off Tatooine but Luke has never heard of the greatest tandem of Jeid knights in the history of the Republic--Obi-Wan Kenobi and Anakin Skywalker? He's never heard of Yoda? Really? For eight hundred years Yoda did train Jedi. But a scant twenty years later he's completely forgotten by, apparently, everyone? I mean, no one in the rebellion, which is crafty enough to steal plans for the Empire's most prized weapon, remembers Yoda? Packing up his x-wing for his flight for Dagoba Luke didn't talk to anyone else?

This didn't happen:

Unknown Rebel says, "Hey Luke buddy, too bad we got obliterated today here on Hoth but we'll get 'em next time! See you at the rendezvous point."
Luke replies, "Oh, I'm going to Dagoba instead."
Unknown Rebel says, "But why?"
Luke says, "Oh, I'm going to see some Jedi named Yoda."
Unknown Rebel says, "Oh! the former trainer of the Jedi? For eight hundred years trained Jedi did he...don't mind me Luke, I guess that's how he talked. But, are you sure about this? I thought he, along with all of the other Jedi was wiped out about twenty years ago after serving the Repulblic for about a thousand generations...give or take." Luke shrugs and leaves.
Growing up on Tatooine Luke never heard of the Jedi? He didn't ever think it was cool that his last name was the same as one of the greatest Jedi ever to have lived? He never thought that "Ben Kenobi" might be "Obi-Wan Kenobi?" Oh, that's right. They don't know about these things on Tatooine. NOBODY ON TATOOINE REMEMBERS A FAMOUS JEDI KNIGHT NAMED "SKYWALKER?!" Really? No one? None of Luke's friends make the connection--and I don't mean that Luke could be related to Anakin but even that they have the same last name. No, Skywalker is Star Wars' Smith. And Kenobi must be its Johnson.
They have computers and holograms and ships that can go into hyperspace and hovercraft and laser guns and androids that can speak eight million languages and yet they don't have any history books on Tatooine. Or in the rest of the Republic/Empire? When Luke SKYWALKER blows up the Deathstar, nobody, NOBODY in the galaxy, upon hearing the news, said, "Oh, remember that one Jedi a few years ago? Wasn't his last name Skywalker too? Say, I think he was renowned through out the galaxy for his skills as a pilot and now there's this new Skywalker kid who flew through all kinds of blasters and was the only one not to get blown up during the assault on the Deathstar and then the sonofagun even blew the thing up and dig this now, I hear he didn't even use his computer and that he 'used the Force' instead. Hmmmm...I wonder."

"No, it must just be a coincidence. There are just too many Skywalkers in this darn galaxy."
