Spelling is an arbitrary, artificial frame of reference.

It wasn't even established in the grammar world until relatively recently when they attached it to the vibrations of a particular sentence.

Without a solid point of reference, it'd be impossible to do any sort of 'writing' since you'd have no measure of how far you've written or in which direction. Kind of like driving on a totally unfamiliar freeway system with no signs or any other method of getting your bearings. Even if you could write on the road, you'd still be a retard.
