Internet Money
You said "ecash" and "Internet Money" but how is this related or may substitute the notion of "trustlessness" ?
providing an explanation of trustless is something for the user guide - you can put it on a website somewhere.
The thing that needs to stick in the memory and come to mind when hovering over the buy button on a merchants store are words like eCash or internet money.
Bitcoin has already done a great job on the decentralised explanation and how it relates to trust. We don't need to reinvent that wheel. People just want to know that the product works like cash, but on the internet.
Do you trust the money in your pocket? You don't even think about it. You hold it and pass it on.
