Updating name servers requires you to go through your registrar and

than switching A records or switching domain names during a spam run.
Creating a completely new nameserver is even slower and I think that
if spammers start to try to flood the root servers with lots of new
name servers, there will quickly be even more restrictions put in place.
Anti-spammers are currently using common name servers, and it is a
useful technique. I think it will remain useful in the long-term.
Agreed. Eventually, in the future Utopia, I can imagine registrars taking
a more active role in killing spammers. If they could get better about
tracking which domains are owned by the "same" people (by actually
verifying addresses or something) and if they actually terminate all the
domain names when a number of them by the same owner are found to be in
error, then this could replace blocking by DNS Server IP.
I think "your NS servers are in the same IP space" is the closest we
currently come to "your domains are controlled by the same person". But
