Over complication is the enemy of safety in aviation, most pilots are the run of the mill average human, who don't work well with excessive amounts of information. Piloting requires simple direct rules that don't need much brainpower, as the act of piloting the craft itself chews up a lot of the grey matter just keeping it upright. Its all fine to have a wad of paper rules to read through, but reality is, half wont read it properly, just skim, others will read it and forget it 10 seconds later, and so on. That is why aviation is full of drills, repetition, do things out of the ordinary and you lob nasty surprises on the others around you.
Half the drivers out there can't even get the road rules right, some of those are also pilots.
Remember there are rules out there that reflect this, like sales contracts etc, once they reach a certain length for inane things they become invalid as the average person will not be bothered to read it, so can't be held to the contract details.
