I think you misunderstood me; I was making an analogy.
All systems have some form of common ground or central point. That does not make every system “centralized”. With the example given upthread, blockchain, there is the development team, or standards organization, which is a central controlling point of the blockchain. Does this make all blockchains centralized? No. In the same way, a common root zone does not make the DNS centralized.
Both suggestions ("blockchain" and "DNSSEC") are nonsensical here.
As you note, "blockchain" is a technological concept. Implementations of a blockchain have varying qualities, some of them are centrally managed by an entity, some of them are based on participant consensus in varying degrees. So suggesting "blockchain" be used to solve this problem is a bit like suggesting "nails" be used to build a house. Sure, it's a component you could use, but you haven't really nailed down any specifics about how the house is going to be structured.
DNSSEC, by contrast, is 100% a centralized PKI system. Leaf records are signed up and up and up, and the root of it all is signatures on the root zones by the operators of those zones. Having a hierarchical structure where an entity at the top of the pyramid signs off on the records beneath is about as canonically centralized as something could be.
The suggestion to use “blockchain” came from user jongjong, not me. I therefore cannot elaborate on it.

Again, my point is that just because something can have, or has, a central point, does not mean it is “centralized”. The DNSSEC root cannot override individual DNS records on the domain or subdomain levels. DNS (and DNSSEC) is federated; i.e. it delegates absolute authority over sections to others, which can in turn delegate authority for domains to yet other, which can in turn delegate authority over subdomains, and so on.
To make an analogy again: The US federal government does not possess absolute authority over the states. The UN does not possess absolute authority over its member nations (or other nations). Interpol does not possess absolute authority over every police force in the world. And so on.
