You could store cash/gold in an anonymous safe deposit, but FBI raid and steal this. You cant fly with large cash because again feds steal it. You can't carry it out the country in large without reporting it.
Crypto, same story, KYC at the exits and P2P offramp actors getting treated as 'unlicensed money transmitter' etc which again triggers KYC.
Quickly you realize it's about shutting off all the exits of privacy, not money laundering which only has increased cost consolidating power to more dangerous organizations.
