Relays are fungible. Exit cost is zero.

"Large proportions of the population of these countries could easily move out of the country if their local rights were violated," and this mechanism is what makes the Nostr relay model powerful. Trivially exit bad relays.
How easy is it to switch home servers in pubky?
You keep asking me questions but not learning anything.
Also, stop quoting people, especially if they weren't even talking about Nostr; speak for yourself.
Watch this if you want your answer.
Thanks for the video.
Pubky exit: "all you need to do is update that DNS record, and the mainline DHT, and change your provider." (What does "change your provider involve? Copying data?)
Nostr exit: "replace the relay in your relay list with a different one."
Nostr exit can be accomplished in a web client without asking any trusted server to do anything. Relays don't have to be trusted *because* the exit costs are zero.
You're right about relay centralisation concerns. Using the mainline DHT is a good solution. Seems like a useful thing to add to Nostr one day.
I don't understand the value of putting pubkeys in the DNS. Is the problem there that you're worried about authorities censoring/stealing homeserver domain names?
I notice that you can now get an SSL certificate for an IP address through Let's Encrypt. What about using the standard BitTorrent DHT mechanism to link to IPs instead of domain names? That's the whole purpose of non-mutable "announce" calls.
Thank you for taking the time to answer my questions, I appreciate it.
