2 - Innocent victims can only be sent bounces if spammers know their
address to begin with, and if you use this system then spammers
can't forge your address. It would also be a simple matter for a
email service provider to filter out this bounces if the user did
not initiate a email to the corresponding address.
So two people using your system could never communicate.
I thought that the issue that you were bringing up was the following: A
spammer forges your address and sends out a million pieces of spam and you
subsequently get an enormous number of bounces as per my system.
I suggest that this won't be an issue as your email service provider will only
allow you to receive one of these special bounces if you had just sent out the
corresponding email.
If you had just sent out an email to someone then you email provider would
allow the bounce to come into your inbox.
3 - The issues with CAPTCHA are addressed in my article
Including the spammer trick of feeding them to suckers in return for
"free" porn? Including blind correspondents?

Both of the above issues are commented upon in the section immediately
preceding the section where I compare my system with other anti-spam systems.
