least at first. For example, give each customer 1,000 stamps per
month and charge for excess, whatever, that's a marketing decision.
D) However, other ISPs can choose to transit or not email with
particular stamps.

choose to reject it.
Stamps buy you nothing in this scenario. ISPs are already free to
reject mail from ISPs they don't like, and throttle their customers to
only be able to send N mails per day.
But they don't do it (some throttle, but hardly any reject based on
ISP, unless that ISP happens to be a spammer masquerading as an ISP).
As an ISP perhaps you can answer why they don't do it?
