They can buy a stamp and keep on re-using it.
Just like people can buy an Amazon gift voucher (which is simply a
code they enter on Amazon's web site) and keep re-using it?
Come on, be serious. One-time-use tokens are a commonplace tool used
all over the Internet. Don't pretend they don't exist or couldn't be
used for e-postage.
You need to explain how a global epostage system scales, and scales
reliably, before making that assertion.
Avoiding both a single point of failure and an N x M problem, while
still having acceptable performance, using infrastructure and staffing
that can be funded by stamps that are a "reasonable" cost is a minimum
there.
Cheers,
Steve
