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.
I was thinking more like a) it makes them feel less like incompetent dolts for not readily escaping their own problems, because, yes, you can disappear, but, wow, what a cost to pay and b) it fuels the imagination that perhaps escape from their current problems is possible (without such extremes of drama and suffering), if they keep at it.
and that is not the ocean, and yes he died
