We have an ADSL monopoly over here, too, but the monopolist is forced
by regulation to offer PPP or L2TP tunnels to other ISPs (think of ATM
reinvented). Something like this seems to exist in your country as
well because several ISPs can use those ADSL lines.
Before that was common place, I got offers for IPsec or GRE tunnels
across the public Internet, based on the monopolist's IP product.
Wouldn't something like this possible in Spain, too?
The last mile carrier is not important, but it's the actual ISP that
takes care of your public IP address and the customers that are
neighboring you.

Well, you do have choices. You've already mentioned several yourself.
I'm sure that many Internet-savvy Germans think that the situation
over here is the same as in Spain--that there's an oligopoly and you
can't get affordable Internet access from responsible ISPs. But this
isn't true. Several ISPs offer interesting ADSL-based products (which
include IP address assignments from RIPE), but you won't see ads for
them on TV. However, there's a drawback: you pay per megabyte, which
basically means: no P2P networks, no day-to-day tracking of sid, no
endless gaming session.

This doesn't scale. If dynamic address assignment is involved, it
doesn't even work.

Maybe there's a comprimse: blacklist, but have the blacklist
overridden for subscribers. I don't know how hard this is to
implement, though.

My MTA can detect most Windows worms only after receiving in the
middle of the DATA command (which is hard to avoid if you think about
it, I'm still looking for the Prophetic MTA). For example, I lost
quite a bit of real money on Swen.A (which uses the ISP smarthost,
unlike most worms).
