As someone who works in the domain name industry, I'd like to note that there is ever increasing pressure to police domain name use. When you buy and use a generic TLD such as "com" or "ninja", you are buying a US product and it is subject to sanction laws and other things you may not realize. CC TLDs (two characters long like "ch") are products of that country and have their own laws UNLESS the registry company is located in the US - in which case it is also subject to sanctions.

I point this out because unless you get everyone using your IPv6 address directly, your name is certainly NOT decentralized.
