I was drawing a distinction between death of natural causes at the end of a (hopefully) long life, and death due to an accident in motorcycle road racing. I did so because the post I responded to did not. By the way, there is nothing wrong with criticising the decisions other people make.
It is ultimately all about making a free choice.
Not a single motorbike rider does the TT under duress. It is their informed choice. They know the risks and the rewards and they choose to race regardless.
Actually I think this issue is bigger, far more important than a mere bike race. If you think certain activities should be banned or castrated because you feel the benefits outweigh the risks then how far do you want to go? What do you think is safe enough? As Simoncelli and others showed last season motorbike racing on a dedicated circuit can be fatal too, should that be banned? How about club level racing where injuries and deaths are far more common than on the sanitised motorsport series we get to watch on TV? Riding motorbikes on public roads? Riding horses? Where would you stop?
For me the TT is an expression of the importance of free will and the fact that the Isle of Man government and people are mature enough to respect it (as well as the quality of the racing of course). The day the TT is banned, and I hope it never happens, will be a truly sad day for humanity as it will show that our tolerance for free choice will have diminished by a very significant degree.
