Yes, but it's a token whose privacy the client controls, rather than the blossom server. So I suppose your earlier point about hiding the content from the server is germane — I don't trust commodity blossom servers to protect user content.

You just shifted trust from blossom server to a relay, same problem nothing solved.
Yes, but the explicit paradigm in flotilla is delegating access control to relays (not commodity blossom servers)
Relays are not commodities? There are thousands of them and nobody knows who is who and user cannot fully control how their note propagates and by whom. Ok, I’ve said enough already, no point of taking it further
