I think privacy might end up being unobtainable.
The blockchain is too open (eg I can keep my secret but what about all my dealings and descendants?) It only takes one reveal in the next few decades even, to expose address history.
The imagine future populists talking up conspiracy by calling early adopters "time thieves" because we got all the cheese and 95% missed out. This would be fuel for "Know Your Bitcoiner" and the commercial arrival of Social Credit. The nature of an address behaviour is all that's needed until eventual unmasking of ID.
And not to forget the unsavoury individuals among us doxxing fellow bitcoiners.
Over time the system could be too transparent and non reversible so perhaps the best outcome is a new form of social regard based on best conduct in a world where we all see each other
Bitcoin is trending towards more anonymous though. Lightning payments aren't even recorded in the blockchain. Mixing services are getting better and more useful. And now Nostr lets you create an account that isn't tied to your identity. You could build an entire reputation in here without anyone knowing who you are in real life. You still have a sticker credit score, with your number of followers, how many people are willing to zap you, and how well you're respected in the community.
True that deanonymizing tech is improving, but so is the fight against it. Maybe it will be a perpetual war, I don't know.
