Even if we accept your premise that no exit operator cares about internet
abuse, it's still the same thing. ISP's define what is acceptable usage of
their internet connections and by implication, what is acceptable usage of
the Tor exit. Tor could ignore what ISPs want (which is usually quite
reasonable), but then "no Tor" clauses in ISP acceptable usage policies
would just become even more prevalent.

It is currently possible and I am aware of proposal 224, which is why I'm
bringing this up now. I don't think this is something that should be fixed
without a *lot* of thought given to the consequences. I am by the way quite
aware of all the counter arguments already, but someone has to play the
devil's advocate here.
