For example, offshore banking is one of the world's biggest businesses. In order for remailers to become commercial on a big scale, anonymous payment systems such as DigiCash must become popular. My predictions came true. Today, many remailer operators charge fees for the same reason that you go to work in order to pay for food, housing, etc. Some people set up remailers for their own personal usage, which they may or may not care to share with the rest of us.
Some persons are educators or activists.
One of the best examples was the great debate about Caller ID on phones. People were really upset that the person at the receiving end would know who was calling. On things like telephones, people take for granted the fact that they can be anonymous if they want to and they get really upset if people take that away. I think the same thing applies for e-mail. Living in Finland, I got a pretty close view of how things were in the former Soviet Union.
