Then why have the magic spells engraved into the wall to keep the NK from crossing? Would you not cast a spell keeping the humans south? Keeping humans south was not a reason for the wall.
it appears any spells cast to keep the night king out, didn't work. i know of no history to prove the spells purpose or if they were there at all. I would agree with your position if every 20 years the NK actually attempted to cross the wall and something repelled him. what we do know is the one time the NK decided to take the wall down, he brought it down in seconds.
questioning why the spells were not there to keep humans out would be typical human arrogance a power like the night king would laugh at. Because we are not worth a spell and easily kicked to the curb would be my thought.
