Very good point.

I've said here, and elsewhere, my opinion of this whole business. I believe that, if we are to have a free society, where people can show their dignity and preserve their right to privacy and happiness, we *must* make people who abuse those rights pay for doing so.

The problem is, if you want e.g. spammers to be traceable, then somebody (e.g. a guy offended by your comments on his website) can fake a spam purporting to be from your IP address and trace it to you.

IP address spoofing could be largely eliminated, if every router on the net were configured to perform a simple sanity check: don't let packets pass that have an "impossible" source address from the perspective of that router.

That is, if an ISP has sold you a range of static IP addresses, its routers should drop any packets from you that claim a return address outside that range. If everyone did this, spoofing would be much more limited.
