[anti-spam-wg] Proposal for a legal solution to spam

Hi,

I came across this:

http://www.freesoftwaremagazine.com/free_issues/issue_06/neednt_eat_spam/

The author is arguing that ISPs, ICANN, RIRs and legal authorities should 
move away from a technological approach to combatting spam, and use what 
powers they have to enforce good behaviour.

Do people think there is any weight to his argument? Or that what he says 
may constitute a threat to the way in which LIRs and RIRs operate. I 
notice that he makes a connection between spam and cyberterrorism, 
specious in my view, which may be used to push his proposal forward.

Regards,

Ian
