Since sheeple will always pick convenience over security, and The State, through regulation, controls what will be convenient, digital cash will never achieve widespread use.
Obstacles don't make something impossible. I refer you to http://inventors.about.com/library/inventors/bledison.htm : "Edison actually had to invent a total of seven system elements that were critical to the practical application of electric lights as an alternative to the gas lights that were prevalent in that day. These were the development of: the parallel circuit, a durable light bulb, an improved dynamo, the underground conductor network, the devices for maintaining constant voltage, safety fuses and insulating materials, and light sockets with on-off switches. " There are many compelling, legitimate, and legal uses for anonymous digital bearer instruments. Their utility far outweighs any negative side effects. If a State disagrees, there are 200 more to choose from. Patrick M http://lucrative.thirdhost.com/
