Well, that's my argument against a communist society. It was designed only for perfectly altruistic people, and that's a kind of people I have never found anywhere. If we want something that actually works, we need something designed for the people that actually exist.

It's the same with the Internet. Once the spammers got the gist of it, it has been a constant struggle between spammers and anti-spam people. We have reached some form of equilibrium, but anytime a new person connects, it's a brand-new learning about avoiding potentially bad stuff. It can be very expensive learning.
