In a word: yes. "Has access to" needs to be defined. Is it at work? At school? Your own purchase? I like to think long-term and be independent. I'd hate losing access to an essential tool because I change jobs or finish school. If I purchase something myself, I also think long-term. What if I progress to larger or more complex designs (EAGLE becomes expensive quickly)? What if I don't want to pay upgrade fees? So yes, there are legitimate reasons to use KiCad even if you "have access" to a more mature commercial package. I don't think there are any reasons to use EAGLE, though.
