I disagree, really a lot of people just *don't care* about being anonymous.
The problem is their actions don't only affect themselves. People with bad habits like address reuse harm, not just their own privacy, but the privacy of anyone else they interact with. It's exactly like pollution.
But this really scare off people. They don't know it, they don't understand it. If we want bitcoin to be more popular we just can't tell them to use hundreds of receiving adresses!
