Agree with most of this. However, torrents and social posts are not quite the same. Torrents are files that are designed to be shared. Posts could have some personal attachment. You could have a business nostr server. You could have a friends group. You could have special articles you want to share only in cretain places. You might share a party photo with some friends, that you regret. There is absolutely no default social contract in nostr other than you are using a websocket API over HTTP. If the system you use gets your consent, that's a different story. But if not, you can have the right to feel violated. Or not recommend nostr. The social contract is largely inherited from the status quo of users owning their own data, imho. Unless you agree to infinite sharing, which is also potenitally forever and undeletable.

I understood that the post button in most Nostr clients does post it to the network. There are no tools in Nostr to limit posting to some groups. You don't select where you post to in most clients, there are preferred relays, not ultimate relays, there are no per note relay sets anywhere in the user interface. It might be used like that in the future, when it's the responsibility of relay to limit writing and reading of notes to those that should be authorized. And that means not allowing connections from relays that could copy the notes. I see what you are saying as a potential problem in the future, but I think encrypted messengers are much better for sharing within a closed circle. Nostr is for public sharing, it's not encrypted, notes don't have any permissions attached to them except for the - tag, which is a self limitation like robots.txt. There's even a tool like http://nostrsync.live/ which will download all notes created by an npub from a list of a lot of relays and try to publish it everywhere. Note that authorization is not required, I can do it for your npub and the relays have no way of telling that you did not post that message to the relay, it's all valid signed notes.
