Real currencies generally exist with a Government that requires taxes are paid in that currency. So there's always a baseline demand. Almost nobody in politically stable countries could completely stop using their currencies tomorrow if they didn't like how the Government sector (Government + central bank) spent money (without moving to another country).

Also, it's different because since currencies have goods and services that you can buy with them, monetary expansion isn't actually inflationary to the price level unless it pushes aggregate demand (spending) above the supply of goods and services available in that currency. Whereas all this Ripple likely is going to straight to be sold off so the recipients can actually buy things...
