Several years ago, there was no technical solution to these problems. Privacy is valuable. For example, offshore banking is one of the world's biggest businesses. My prediction came true. 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 email. Living in Finland, I got a pretty close view of how things were in the former Soviet Union.
