[Star Wars] Why did Obi Wan blow 20 years of hiding on Tatooine by using his lightsaber to cut off the arm of the guy who hassled Luke at the Mos Eisley cantina?

I was just watching clips from A New Hope and a certain scene jumped out at me. In the Mos Eisley cantina when Obi Wan takes Luke to meet Han, Obi Wan uses his lightsaber to cut off the arm of a guy who was hassling Luke.
  
So Jedi have systematically been hunted down throughout the galaxy and Obi Wan has been in hiding on Tatooine for the past 20+ years, successfully evading the Empire, but now he just blows all that by whipping out his lightsaber and maiming some lowlife thug who could have easily been dealt with in a much quieter manner? And in an establishment filled with bounty hunters and criminals who would no doubt report the presence of a Jedi for a reward no less? Why draw attention to himself like that after all those years, especially since he was trying to get himself and Luke off-world rather covertly.

I know it's probably irrelevant, but it just seemed kind of odd to me.

Because he was going to Alderaan anyway to initiate a Rebellion against a Galactic Empire. And this drunk peon on some shit hick planet is getting rowdy with the enemy Sith lord's kid, his past padawans kid, who is now under his protection. He's Obi Wan. He was making a statement. Bitch, the jedi aren't dead yet. We're just getting started.
