From the insidious "tweaking" of behavior with small discounts and price hikes to the open totalitarian refusal to allow one to buy or sell a particular good or exchange with particular persons, nothing good at all could come from CBDC.

This is all compounded by the fact that the government issuing CBDC could simply remove it from your bank account if they deem the funds too long idle, a far more direct method than inflating it away.
