At the current time, proponents of eCash are somehow thinking very altruistically and they sort think people are going to run mints for free for friends / family. I'm doubtful if it works out like that.

Regardless, the simple way to protect yourself from debasement is to "dip in / dip out" of eCash....that is don't hold it for more than a few days....it should just be a "transactional currency" and not something you hold. This way any secret debasement will not affect you during that short period.
