My point was that a larger and larger proportion of the things we buy we buy over the internet: it is something like 25% of all consumer purchasing now. Those transactions are cashless.
Some types of goods you can only buy over the internet, like software, and this trend will only continue.
I think MoneyGram/Western Union are a great counterpoint, but while anonymous, I consider that more similar to cashless than cash: you have to input cash into a machine and… transmit it over the internet.
I also agree it is not a binary thing.
