The first name being the valid one makes sense and dose make use of bitcoins immutability.

A) The issue is the blockchain size and the ability for users to verify names themselves. If the solution requires people to write distributed servers that index these names. then we are back to where we are now with DNS servers. it wouldn't solve the censorship issue because all phones/wifi routes are programmed to point to a DNS server and cant verify anything themselves

B) True, things would be more secure with better key management. but just as you have multiple password across multiple sites to reduce the damage when you get hacked. You would want to have multiple npubs for social/dns management, which kind of defeated the purpose or at least one of the big selling points of this system.

The use of the blockchain to tie names to public keys is novel. but It could only solve the "permission" part of the DNS problem. It cant solve the censorship problem because the only way to verify the names on the blockchain would be download all of it and index the names starting from the earliest.

And while servers can do that easily. no consumer device can easily do that, and so they would have to fallback to trusting a third party (which is where you get censorship)
