I get it 100%, Thats a real problem hive has with the social layer + finance. A "hide" option would be really a thing and something long term to consider (some zk wallet inside). It should be kind of easy if its a 100% trusted onchain pool IMO and it could have features above ( imagine % DAO voting, so it could be Anon power). I think something worth to think about since that has downsides too if it becomes a more complex tool.
Same with HBD, I think privacy is very important, special in Ai age ( a google search is basic, with Ai it gets worse with leaked data). And if you combine that with posts and other meta data, it can become even worse.
To smart contracts, yeah i think most people on hive dont really know what is on the roadmap. I would recommend from the core team to make a simple info graphic from time to time to show what is planned. Like something to share and see in 30 sec time.
Magi itself is not really a smartchain and it has high potential to not deliver ( i hope for the best).
