There are points worth considering on both sides regarding file sharing and copyright.

However this censorship action is being taken in the name of 'homeland security'... I find this a very disturbing trend and wonder how this community feels about that.

Watch them start banning ISPs then, or taxing their upstream links

Still, distributed DNS is great -- but we would then have to trust certificate authorities that grant certificates for a certain period of time. If the certificates never expired, then domain ownership would be forever. If they did expire, then the government could forbid a certificate issuing authority to reissue a certificate, but the effect would be much sower than banning dns.
