> You just described the benefits of a cash transaction.
Nobody is denying cash is good. But cash relies on the government issuing it, can't be sent through the internet, can't be transported across borders easily, or in large quantities, can be physically seized, etc.

Yeah and what's stopping them from throwing you in jail? Or just killing you?
I'm assuming an intermediate point here, in which the government isn't either fully libertarian/anarchist, neither fully authoritarian. Which is what most "free" countries are like nowadays.
If the government is fully authoritarian and you're an "adversary" you're fucked.
