Well, you have fun doing dungeons right? Well, why not do different orders to (potentially) have more fun with that? It's not like doing dungeon 1 should and can only open up dungeon 2. Remember, this is The Legend of Zelda, not a schooling system or Mario. In school, you can't jump straight to Calculus III (the final dungeon), you have to do Algebra I (dungeon 1) then Algebra 2 (Dungeon 2), possibly Alg 3 (Dungeon 3?) if your school offers it or go to PreCal (Dungeon 3/4), then Cal I (Dungeon 5), Cal II (Dungeon 6) then FINALLY you can do Cal III (Dungeon 7).I do the dungeons because they are fun. But what does this have to do with ordering?
Sorry, that's just a thing with me...going out of order in a game is like reading chapter three in a book before reading chapter one and then skipping to chapter seven.
TLoZ is supposed to offer us a world (or at least, that was one of the intents with the original game), and part of a world is being able to explore, do things our own way. Of course there will be limits (maybe you can't do the final dungeon before the preceding ten or so dungeons), but beyond that why should I be restricted to doing things in the same order each and every playthrough?
I do like your analogy to reading books, but dungeons aren't and shouldn't be sequential like that in my opinion.
