I think I offered a pretty concrete example of a real situation and how the imagined utility of crypto magic isn't actually all that helpful.

Now, perhaps what you're suggesting is "I've got millions of units of money that I've acquired through locally illegal means and I want to transport that money someplace else and I don't feel like renting a private airplane and diamonds up my prison wallet are uncomfortable and I don't want to pay taxes or otherwise explain why I have a brand new S class I paid cash for." then yes, I'll accept that there is some grey area where crypto has a place (to explicitly work around legal regimes I dislike, would like to degrade further, and don't feel like dealing with).
