It’s worth pointing out that an unfreezable asset does no good if it can’t be spent. In 1945, Finland, who had managed to fight the Allies, the Axis, and the Communist bloc at various points in WWII, had a population sitting on piles of cash (goods were rationed during the war) and few things to buy with them. Fearing a burst of inflation similar to what the US experienced post-COVID, the Finnish authorities came up with a novel way enact financial repression on otherwise censorship resistant cash. Effective immediately, all large denomination bills were to be cut in half. The left side was still cash - worth half the face value. The right side was now a 4-year bond yielding a paltry 2%. Needless to say, Finland still suffered robust inflation (well above 2% paid). It also left bank accounts untouched, for reasons I’m not clear upon. As you know, most of the monetary base is made up of bank deposits, not physical cash. But it’s a good example of how even if the asset itself has no freeze or burn function, if those who would otherwise accept it in payment can be squeezed, you still have a problem.
