I brought up the design of Tor as an analogy for the design of Nostr. It's irritating that you only considered how Tor can be used for Nostr rather than the general design of Tor itself, but I'd rather drop the topic than try to spell out the analogy better. You are right that if a Nostr user's privacy is compromised, that can be leveraged in order to censor their speech. It doesn't matter how many relays are willing to publish a person's notes if the person in question is being imprisoned and physically prevented from posting those notes. However there are many existing privacy technologies that can be applied here. The most robust protections focus on protecting the user rather than the relay. Why agonize over finding a relay owner who will resist torture to keep your IP address when you can just avoid giving them your IP address in the first place? Personally I use a VPN because it's easy and convenient, but there's no reason a person couldn't send notes to Nostr relays over Tor or I2P or from a burner phone in a remote field. If privacy is the issue then there are lots of options, but if the issue is finding a Nostr relay that you know for sure is trustworthy, then you have no options at all.
