Maybe you missed the news, but apparently the USCG is looking at investigating the world record attempt and subsequent fatality, and there is a good chance commercial charter vessels will be impacted by this. No matter what, it is likely that liability insurance rates will go up in response to the subsequent lawsuits that will be filed over this whole fiasco.
And don't fool yourself into thinking that there will not be any lawsuits filed. A lawyer has already stepped into the fray.
Now tell me again why anyone who has more money than sense should be allowed free reign to kill themselves?
Because how you live (or die) is IMO a fundamental human right, as long as you're not hurting anybody else with it. As somebody else said above, as long as they foot the costs and don't take anybody else with them, let them have their fun.
There are assumptions that he "had more money than sense" and that he was footing the costs. Are we sure either is true in this case? I don't think so at all. A quick Google search suggests to me that neither was true.
