Total government control over your possessions by forcing you to not save them materially on your side, but exposing them to bank and state plundering - your savings, pensions, money, everything, in digital format and thus being able to make you pay for anything the government sees legit - hows that as a motivation to insist on cash money being kept, eh?
In other words: freedom.
All my savings and treasury - is not at the bank anymore.
There are reasons why they try so unforgivingly to kill cash money, the Rogoffs and Bernankes of this world.
Wake up. I am not caveman from the stone-age.
