Maybe the question one should ask themselves is:
If I died while sailing, would it have been worth it. If the question is "NO", then I would pick another hobby that is either safer or "IS" worth it.
Another thing to think about even some of the most experienced sailors in the world with the best equipment and training have died sailing. The other thing when things start to go wrong, you cannot pull over, stop and get help like in a car. If you are on an ocean passage, you could be hundreds of miles from help. And even if help were to arrive, that could only be the begining of a long rescue.
The key is to manage the risk through equipment, training, experience, and weather and sea knowledge. But in the end, bad things can still happen, and when they do, it is a much more difficult situation than if you were on dry land.
