It seems the author overlooked the possibility of writing out the full binary string of whatever format he'd like (i.e., "zero one one ..."), prefaced by instructions on how to parse that.

That would give you great "authenticity" (in his definition) and great longevity.

Not practical for reading back, but that was not the point. With the help of a few simple scripts, writing is easy. So, in the end, not really an argument against storing information exclusively in plaintext.
