yes, don't use the thieves' mint

that's a non-solution for the actual real world...
Ecash is a transactional medium, and is not meant to be held in large quantities. Above example shows how it enables offline exchange/ATMs. If you're running the ATM you own the mint and have no inflation risk. If you're a user, the risk is that they rug your transaction. The same risk applies for every other exchange, except maybe for atomic cross-chain swaps.
