Arrays aren't just used for counting though. For example, the origin in cartesian coordinates is "0,0" and not "1,1". Not to say that I disagree, I don't think I've come across a situation where 0-based indexing would have been better for me personally. But there are definitely a lot of situations where I can imagine it would be preferable, like pretty much whenever you're doing math with them.
