@Wolfwhistler You are completely wrong. Most fiction makes an attempt to stick close to the home because otherwise the audience can't get into the story and can't sympathise with anything going on in it. That's why in the most famous science fiction, for example, the people and great many aspects of life are exceedingly similar to our own reality, only the folks have fancy direct energy weapons, spaceships, and other external technology. Cyberpunk is breaching the limit a little bit, but even that isn't really out there. Intelligent aliens mostly behave in ways we can easily understand. AIs either don't play much of a role, they mimic humans, or maybe they control some killer robot army in a very one-dimensional way. Because the truth is that humans are incapable of imagining a true artificial intelligence, so it won't make a very good story (assuming a talented author somehow could depict it believably (although nobody knows what's believable there)).
Fantasy isn't that much different, which is why it's most of the time in the same old pseudo-European historical setting. The vast majority of authors don't bother to make the various fantasy species/races any different from each other, apart from some external factors (like pointed ears or animals ears).
So, yeah, fantasy is jam-packed with limitations. They are there for a reason, not because of pointlessness (whatever that would mean).
I do agree on this being pointless to argue about further, however.
