'Civil liberties' are only meaningful in the context of a specific
'civilization'.  Welcome to the civilization that allows spammers to use
dynamic IP addresses to disrupt, annoy, cause harm, commit commercial
and all other sorts of fraud.  It is not a perfect civilization, but
it's the one we have, and trying to hide our heads in the sand about the
*real* problem these restrictions are trying to solve isn't going to
make things much better any time soon now.

One may easily argue that the 'civil laws' that forbid stealing from
other people are 'limiting the freedom we have to use the potentially
boundless resources available all over the place'.  I don't think anyone
would consider the argument in favor of stealing as very sound.

The same can be said of the IP address space.  One can argue for days,
for weeks, or even _years_, that requiring a static IP address to be
able to post to a 'common resource' --like the mailing list-- is a limit
to the freedom of everyone.  I'm not very convinced this limit is as bad
as you are trying to describe, though.  In particular, I am not really
convinced the 'freedom' of everyone to post from non-static IP addresses
is worth the immediate problems this would cause by massively increasing
the problems we have with spam mail even today.
