Well, in that case, it is becoming clear what the solution for blocking
spam, WHILE also keeping collateral damage to a minimum.

This solution is also viable for both the end-user and not hard for ISPs
to implement, so adoption could be high:

Dialups and other "dynamic IP" resources should go through the ISP's mail
server, since services like Spamcop would have to constantly block new IPs
as the spammer keeps redialing and getting new IPs.

Static IPs can send email directly, as these are usually allocated to the
spammer "permanently", and if the spammer spams from his IP, then Spamcop
can block his IP properly, and he can't just get a new one.

This works, because most "dynamic IP" services like dialups tend to have a
low connection speed, and hence, any spam that does get through before it
is blocked (or taken care of by the ISP) is minimal. Most damange, as
mentioned, would be through high speed connections, and they tend to have
static IPs (or at least mostly static IPs, even if the IP changes every
week or month).

So, that would be a solution that would make everyone happy, would it not?
