this is the exact and very obvious point missing from the article, which makes me very skeptical as to the intentions of the writer.

since all mail will now have a unique tracker on it, all the issuer need do is log who purchases which stamps and you can now track who sends mail.

this could have a chilling effect on many areas of society who communicate via items or letters sent in the post, as the anonymity and neutrality of mail is eroded.
