The prime difference between now and then it that people and capital are infinitely more mobile.
If the same were to be attempted today they would be able to go straight to my door. They would also find it empty as I'd be in the nearest country that wasn't pulling crap like that.
The money would be flying out of the nation at an unprecedented rate. People would be smuggling gold so quickly as well it would be wild, boats would be leaving everywhere lined with the stuff heading to more economically friendly nations.
I hope.
Honestly if a nation pulls this shit again it would be intriguing to see what happens and how much they suffer Economically for their arrogance.
