The right tradeoff: customer has the right to use port 25 but can 
voluntarilly delegate the authority to block it to the ISP.  It is even 
reasonable to default to blocking (with some kind of disclosure) until the 
customer requests a change.

This is no compromise with freedom and it works.

That's what my former ISP did.  It transfered my line to my current
ISP and the non-blocking continued but I don't know my current ISP's
actual policy.
