Don't you understand? None of that will matter in a crypto currency based economy.
The only reason you need to deal with fiat now is because few accept crypto, and none pay crypto.
Think beyond 10 years. Think beyond 20.
A crypto currency based economy would still not be exempt from all laws. And if laws can't be imposed it will be illegal. And if it is illegal then you will see no 'crypto currency based economy'. Wake up.
governments are not almighty.
they havent forbidden cash (ok some are trying to limit it)
they havent forbidden gold
as soon as an economy is using it, they want to tax it - and not forbid it
In your utopia, do you honestly think governments are going to let a anonymous currency get traction in their country so it has the possibility of hurting the nations economy? Just because "they want to tax it"?
And don't give me that bullshit about cash because it is issued by governments.
A government will "let an anonymous currency get traction in their country" in order to forestall a revolution and ensuing regime change.
In Wences Casares' scenario, the first country to defect from the petro-dollar world order and adopt crypto is one that has *ALREADY* been damaged beyond repair by fiat and central banking.
By taking a chance on crypto e-cash, a devastated basket-case economy like Bolivia, Haiti, Ukraine, Venezuela, or Argentina has nothing to lose and everything to gain.
Once a national currency offers/approximates the safe harbor guarantees of Bitcoin/Monero, others will fall in line like dominoes as Gresham's Law penalizes late movers and lavishly rewards first defectors.
