Why is that?

It's not my contention that it could be done in practice, just that the 
ongoing "discussion" about a "new email paradigm" based on pricing 
email, email postage, etc. as a IETF standard to thwart spam might have 
more than a technical consideration to its implementation (which doesn't 
mean a programming language, but how you'd get millions of server and 
billions of users to cooperate and adopt it worldwide).
