@hightor,
My point is that what a society will allow, or forbid, depends on the values of the society. Without the society... your values are just a set of rules for yourself that don't mean anything to how you relate to other people. Morality is useful because it is a
shared sense of rules and values that define how you relate to the other people in your society. The fact that the same rules are imposed on all of us is what makes them useful... the very definition of civilization.
Any society has moral rules relating to the big issues that define human existence; life and death, sex, property. These rules are different from society to society. But every society regulates all of these things.
Here is your logical problem.
I think you are agreeing that we should regulate to prevent people from the "spectacle" of suicide for entertainment. You would be preventing people from making as much money as then can for their family by killing themselves in as dramatic a fashion as possible. The fact that you don't want to imagine this type of spectacle is irrelevant. The question is would you prevent other people from participate.
I am poking at your absolutism. It sounds like you are willing to regulate some aspects of how people end their own lives... if only to prevent this perverse spectacle.
Am I right?
Of course, once you accept that society can regulate this, then we are just arguing over where the line should be drawn. You guys are all arguing from an absolute position... the more interesting argument is for true euthanasia... where you accept the right of society to prevent suicide for some reasons, but allow it in cases of extreme hardship or pain.
