NATHAN COPPEDGE VIA QUORA
It's not so much that it was banished, as that it requires great skill.
Perhaps the reason a high standard is held is because otherwise some pretty dangerous things would happen, like accidental explosions and permanent craziness.
Many people seem to lack a base of knowledge for magical ability. It can't happen by accident, like it would happen for these people. It can't happen by luck.
Another explanation is that some people are somehow unconscious, or too primitive in consciousness to even understand the effects of magic. In that case, magic doesn't happen because it is too much of a privilege to matter to most people. It requires a high degree of consciousness in other words, and humans are still sort of like animals.
The biological explanation is that humans are animals, so in the magical realm you have to exhibit the properties of a god. In that case, illusions are possible but not real, and not easy. Real magic is very hard, sort of like randomly teleporting by accident. Almost impossible. I disagree, though, but that doesn't mean I'm ordinary by saying this.
Even if life is not perfect, we can at least reason that if anyone has control, they're doing their best relative to their own evil (or good).
And, by the way, 'BANISH' is a highly technical word to use for such a general subject. A philosopher like me would rather ask, 'WHY DOESN'T MAGIC EXIST' and if it turns out that it does, then --> 'END OF PROBLEM'.
Difficulty could be explained for any number of reasons. It could even be the result of some advanced beings very specialized mistake, bargaining with laws or something like that. We're supposed to forgive everyone a little bit, so they think it applies to them too. But that doesn't mean they should be punished. It just means there should be more adequate laws. Laws that allow magic and guarantee everyone's safety.
Like the rule of subjective isometric levitation, for example. But this requires making sure that people aren't eating each other, etc.
There may be some basic problems to solve, and part of the problem may be that someone is enamored with puzzles to begin with, before the rules are even defined.
One further explanation is to fault the education process, or fault automatic answers. At that point, it becomes pretty difficult to refute.
But, if everyone voted for paradise for a certain amount of time, and is willing to make reasonable compromises, then after a certain amount of time, all problems should be solved, no matter what. So, the higher powers must be evil, or they must be foolishly justifying some specific set of reasons, in spite of all real compromises.
Perhaps the real powers lost their power, and this world is what we are left with.
We aren't necessarily aware of the worst problems that have happened to anybody. Some of the great powers may think they have a bigger problem than we do. Or not. And it depends on that. So when knowledge is denied, we lose everything (potentially, and actually with an arbitrary gradual process like education).
