Imagine a situation where a 'privacy-chain' is adopted by etfs and governments. It could be a nightmare. Like I wrote in my post it's extremely unlikely that wall street and government would volunteer transparency. So everything would be 'hidden'. Then government and wall street get together, fund research, hire cryptographers to exploit the stealth cryptography... to find an inflation bug for themselves. If there's even a small chance of this happening I think it could potentially cause concern. Bitcoin more transparent.
