Well the rivalry, Sasuke, and Sakura were all added at the same time so it makes sense for them to be linked. I don't really like the fact/revelation that Mr. Kishimoto never really grew beyond that for her or how she was supposed to relate with Naruto, I tihnk it cheapens both of their characters that the only reason Naruto cared about her was the Rivalry with Sasuke. It does add a LOT of fire/fuel to the whole Naru/Sasu thing.
Maybe it does cheapen them, but at the time, he was young, angry, and wanted to be like Sasuke. Logic isn't exactly strong in those times, especially for Naruto. And given Naruto's perchance to seemingly forget stuff at the wrong time, the reason he was chasing Sakura probably fell victim to his forgetfulness -- remember in the beginning, Naruto couldn't have told you why he liked Sakura, not until after he posed as Sasuke in order to find out what she thought about him. And for the life of me, I didn't understand what he saw, because from my perspective, he likes her because she's willing to do anything to get Sasuke's attention, which isn't a good position to be in, liking someone because she's hot in the pants for someone else and won't stop till she gets her man. Not unless you like being cuckold/NTR'd.
