The reality is that current digital money technology takes power AWAY from governments, rather than giving it TO governments.
Current digital money technology--for example Bitcoin, but there are many others too--enables freer flow of trade in much the same way that the internet enabled freer flow of information.
By “digital money”, most are referring to the chain of IOUs stretching from the Fed to your debit & credit accounts - a line of debt, with every penny tracked for who owes what to whom, and traced far enough is clear it all belongs to Caesar.
Yes, Bitcoin exists and is a viable attempt at a mathematical equivalent of gold, being completely anonymous (though what a bitcoin’s inherent value is escapes me) and a supply growth rate approximating GDP increase. It remains viable only because, to my ongoing astonishment, governments haven’t banned it yet.
Yeah, Bitcoin and its imitators are great....just don’t try to buy a loaf of bread with the stuff.
I have not carried cash on me for at least ten years. Debit card or credit. I can buy anything from a loaf of bread to a car if needed.
