Other girls also do not follow the protagonist, so that's one more reason why it's not a harem even by your definition. Or maybe is Haganai a harem after all? Rika is more than open about her intents, Maria's sister is showing more than a bit of interest in him and Yukimura would happily bend over and is probably just confusing love and admiration with her broken mind.
I'll say it again, you generalize too much. For SAO to fit into "harem" genre, even as one among others, the girls and their feelings would have to last beyond their 20 minutes/30 pages.
