Huh?

Running a transaction system that has to handle billions of
transactions a day is a notably unsolved problem, and not for lack of
trying.  The synchronization required to deter double spending of
coins or stamps or whatever you want to call them is inherently very
difficult.

On the other hand, if we're allowed to wave our hands and assert that
it exists, please assert me a rainbow pony at the same time.

Please don't tell me that it's news to you that the DNS is read-only.

You're describing rate limiting outgoing mail from a network's own
hosts.  It's not a bad idea, lots of ISPs do it, and it doesn't
require stamps.
