I fear for a future where financial privacy is non-existant. While I recognize the potential for abuse and enabling for bad actors to skirt laws, I think it should be private by default with measures that allow for auditing. For example, Monero's ability to publish view keys. Sadly, I think many governments will instead rush to the authoritarian option instead.

Edit: if someone wants to enlighten me on why I shouldn't worry about the surveillance capitalist dystopia that's slowly rolling out before our eyes, I'd love to hear it.
