Comments of chapter undefined of Throne of Magical Arcana

Here i am thinking, why didn't they make boundary, limitation, requirement or regulation before allowing them to read or learn those mind blowing topics, for example: should there be a warning like "need to learn this x book or able to accept this and that," so it would make them have more preparation at least and slightly accept the facts that will reduce the chance their head explode. It just crazy how easily and freely people to get access to the books/jurnals despite the risk. I guess this is the perfect case to say "you don't need to know before you're strong enough" or "you don't bite off more than you can chew".
