Bitcoin Privacy - Should We Change the Cryptocurrency Layer?

Do you still believe that Bitcoin should become private by default, or should we find these nice tricks and work around to create more plausible deniability on an open ledger? Well, I think the Bitcoin protocol, as it is right now without any changes, can be used in a very private way just by changing the way that we interact with the protocol. And I think that the privacy by default will come on the wallet layer. Like Wasabi or Hidden Wallet, wasabi 1.0 was definitely a grand experiment, and nobody could stop us from doing it.
