There is a fear imposed on society - unconscious and uncurrent - to not use magic in any purpose. In a way it might be some protection to a degree... because people fear that magic wars may happen then: low people using magic against the others... and governements or religious leaders! (I'm pretty sure that they have magical and non-physical in general protection in case of some extraordinary units having an intent to attack them in a beyond-physical ways). I suspect that this is where this overall antipathy to magic comes from. Barbara Hand Clow states that they also use astrology in order to strengthen their endevours in manipulation of the reality - in any sense.

But when magic is believed to be non-existing, as it is now, leaders are pretty safe (they may only expect attacks from well informed groups).

However, I believe people should start using magic in the new millenium.Ultimately, it helps to bring them back the real identity when dealing with inside and balances their personalities this way, instead of powerlessly dealing with outside only. Obviously, like with any power given, crimes would show up, at least at the beginning; using magic against others, or even attempting to kill them. This is part of this fear which stops people from interest in such fields. But who said that the full idea about magic should not be part of this magical education?
