Austin Clay appeared in court after being charged with felony vandalism for the July 25 incident, which left chunks of concrete strewn across the sidewalk in front of the Hollywood & Highland center.
According to the Los Angeles Police Department, Clay fled the scene after destroying the star but later turned himself in to Beverly Hills police.
"I don't personally think that there should be any charges brought against me," Clay told reporters outside the courthouse. "Because what I did, I believe, was a rightful and just act.
"I think that the repercussions of it were only positive," he added. "I only wanted to bring about positive political change."
Clay is due back in court on Sept. 21. If convicted on one count of vandalism as charged, he faces up to three years in jail.
