You assume all extra copies are worth the same. They are not.
There are at least two types of extra copies in the case where we're
discussing (A replies to a message of B, sending a copy both the the
mailing list and to B):
1. A is too lazy to verify the recipients of the mail, and sends a
copy both to the mailing list, and B.
2. A wants to urgently notify both the list and B about something.
#1 is of no use to B. #2 is extremely useful to B. If there are too many
cases of #1, B might implement automatic stripping of duplicates. This
will prevent #2 as well. This is a huge loss to both A and B, and makes
e-mail that much less useful as a communication medium - just so that
that A doesn't have to do a few seconds of extra editing in case #1.
There is also the moral issue that doubling someone's bandwidth usage
and expecting them to do the work of dealing with this is, at the very
On the other hand, this has been discussed multiple times already, on
debian-devel, and the developer's reference summarizes this in section
4.1 (the relevant part of which has already been quoted). I apologize
