If your threat model includes the threat that Five Eyes governments will try to (legally, or otherwise) commandeer the DNSSEC infrastructure (and, more easily, the CA system) to actively attack users accessing your server, then it is perfectly reasonable to "give up on .COM, .NET, .ORG, .UK, .IO, .CA, .AU, and .NZ". Under such a threat model it would also be prudent to never visit a Five Eyes country, or hold any assets there.

Depending on your use case, a better approach might be to host your server in the Tor network, in which case NameCoin would indeed make some sense:
