What really bad is when a police or any arbitrary guy representing a state can order to freeze all the cards and bank accounts for an individual. This is already happening in Russia and is used not only against political activists but sometime against arbitrary persons through police bribes by their enemies. If a person does not have savings in cash, he or she may loose access to all his money in a moment and it takes often weeks to fight those illegal freezing orders. One can literally starve while doing that.
- Vendors not needing to carry cash, significantly decreasing (or even eliminating) security-related risks (e.g. grocery stores/bus drivers getting robbed)
- Removing PoS that affect quality of service for the actual service provided (e.g. someone paying the bus fare and holding up the ride)
- Reducing the possibility for criminals to launder dirty money (the flipside of the privacy aspect).
