truely private comunication is the abdolute and fundimental requirement for a healthy civilisation
and the archiological record is strewn with the evidence of human endevor to achive a private and reliable mail system going back to the very first
attempts at symbolic representation of ideas
the failures and pitfalls were known from ancient
times,and in the case of the Mongol tribes,there were some who looked down on the tribe of Temugin
and his decendents,because they would write things
on paper,as "literacy" was seen as proof of a weak
mind.....
face it,secure absolute trust comunication,or fatal dependencies....on the civilisational level
