I am not suggesting these mental models are accurate. But it does seem to be harder to intentionally disappear these days. I think our fascination with such stories is similar to or related to our fascination with prison escapes and people who successfully disappeared on purpose.

I think a lot of people feel trapped, like prisoners of their lives. The idea that you could go for a boat ride or show up at your regular job and be just swept away contains both an element of horror and an element of tantalizing possibility. People often long to start their lives over, to walk away from their troubles. They read stuff like this and perhaps feel a mix of hope that it might actually be possible and validation that the cost is very high. It may make them feel both more at peace with not yet having escaped and hopeful for a better future for themselves.
