Because Naruto clearly wants to be like the dude who killed his parents, indirectly caused the Uchiha masacre, killed Neji, and started a world war.
JK, JK!
Seriously, Obito was modeled after Naruto - when they were little they were almost identical, with the hair and the goggles - heck even the clothes were similar. So it's not really a surprise that when Naruto's grown up he looks like a grown up Obito.
