A thought on the basis of things in general: ALL fiction is rooted in some fact, a fantasy world, ignoring the fact that it's one carrying the FF torch and all that goes along with that, has to have rules, and for the sake of making it easily accessible and enjoyable to the majority of people drawing on laws found in our own reality is how it tends to work.
Yes those laws can be modified, but to toss them all into the marble bag and pull shit out at random and see what happens will make people put away your book/game/movie.
Ask yourself, honestly now, when is the last time you read/played/watched a movie, a work of pure fiction that strayed from our own realities natural laws so wildly as to say that the majority of the time wind is detrimental to fire or that dark and light can occupy the same space at the same time. The last time that people walked on space and breathed stone, swam in fire and were burned by air? These things feel horribly wrong, you can tell me all about how they don't but deep down you just know it's wrong. The suspension of reality in a fictional work is more a matter of allowing a person to easily transition into a fantastical world than it is about creating a world that has wildly unique laws of physics. The more a person has to "learn" to accept the fiction and understand it, the less enjoyable it will be, and this leads to it being placed on a shelf behind that 1992 copy of CompTIA Server+ in a nutshell.
